Introduction


We're starting out 2015 with a bang. The time for deliberation is over, and both Samsung and HTC are about to pounce on the market, hoping to slash as big a share as possible. But if your current daily driver is starting to feel a bit dated, and ready for an upgrade, it'll be up to you to pick between the two teams, and that's hardly ever a trivial task with high-end devices.

With the Galaxy S6 edge, Samsung is impressing upon the public that it is both capable and willing to change if its fan base (and stock holders) requires it to. To that end, the Galaxy S6 edge comes in an unmistakably premium unibody that fuses glass and metal together and adds a display such as we have never seen before – one that has both its sides sloping towards the edges. Better yet, Samsung has finally addressed complaints relating to its heavy TouchWiz overlay, with a number of optimizations having been carried out. All of this is rounded off with some truly bleeding edge hardware having found its way under the screen.

On the face of it, HTC's efforts fade in comparison, as despite its One M9 still commanding a respectable lead in terms of craftsmanship and overall design, the S6 edge isn't far behind. The Taiwanese maker has focused most of its attention on one single area: the rear camera. Indeed, gone is the under-performing UltraPixel camera, and we're now looking at a more impressive, 20-megapixel unit that the company hopes will position its flagship better than ever before.

So which one is the better buy? Let's dig in and find out.

Design

Samsung outdid itself with the Galaxy S6 edge's design, but as much as we like it, it doesn't come close to the One M9's aura of classiness.

With every new Galaxy S release, Samsung has historically built upon the base by refining what's already there and adding some extra on top. This time around, however, the company wasn't content with just another evolutionary change – it went ahead with the clear aim of revolutionizing its smartphone design efforts. To that end, instead of the plasticky shell of the Galaxy S5, Samsung has adopted a metal frame that hugs the device and its sloping screen all over and nestles within two sheets of Corning Gorilla Glass 4 – one placed in front of the curvy display, and the other to protect the rear. Samsung didn't stop there, instead opting to carve several 'nano layers' into the shell. The result is a _phone_ that reflects light in different hues depending on your viewing angle. As it comes down to taste, this can be viewed as either ostentatious and tacky, or unique and attractive. Regardless of which group you fall in, it's quite likely that you will not appreciate the ease with which the rear smudges – just a few minutes with the _phone_ leaves the back a complete mess.

However, for all of Samsung's admirable efforts, and despite the undeniably sexier-than-ever-before appearances of the Galaxy S6 edge, the One M9 still remains the more stylish pick of the two in our eyes. What could spell trouble for HTC's new flagship in the eyes of others, however, is the lack of visible changes. Indeed, despite its enjoyable looks, the One M9 remains a very similar device to its predecessor, the One M8, which, in turn, felt a lot like the One M7 before it. We certainly understand that the One line's design can be seen as timeless, but we nevertheless can't shake the feeling that we're looking at only a slightly redesigned device compared to last year's offering.

In terms of physical footprint and ergonomics, we've got a slight advantage for the Galaxy S6 on the first count, and a lead for the One M9 on the second. That is, while the S6 edge touts a slightly larger display, its dimensions of 5.59 x 2.76 x 0.28 inches still read a tad better than the M9's 5.69 x 2.74 x 0.38 inches, and specifically in terms of thinness. But a slim profile doesn't equal better handling, and that remains strictly an HTC domain. Indeed, the edgy sides of Samsung's flagship are a tad uncomfortable to hold, not to mention that the heftier depth to the M9 and the rounded rear shell make for a more ergonomic grip

Display

In 'Basic' screen mode, the Galaxy S6 edge's panel proves far superior to the one of the One M9.

The Galaxy S6 edge and One M9 both stick to the same display sizes introduced by their predecessors, but the two still differ vastly. With its new flagship, HTC is again making use of an S-LCD3 panel with a 5-inch diagonal and 1080 x 1920 resolution – good for 441 pixels per inch. In Samsung's camp, we're looking at a 5.1-inch Super AMOLED display that slopes to the sides, but unlike the one embedded within its predecessor, we now have the whopping 1440 x 2560 pixels, or an even greater pitch of 577 ppi. Regardless, do keep in mind that due to the small physical size of these screens, that supposed advantage in pixel density is almost entirely limited to bragging rights on paper.

Speaking of what's on paper and what's going on in reality, let's talk about color calibration. With the Samsung Galaxy S6 edge set in the non-default Basic display mode, we're looking at a spot-on color temperature of 6800K (6500K being the desired optimal value, but 6800K is considered extremely close), while the One M9 offers the unsatisfactory 8100K. In real terms, this means that the One M9's display is cold (or bluish) and that's especially visible with whites and the various shades of gray. In comparison, Samsung's device offers realistic whites that are... well, white!

Were we to draw the line right here, the One M9 would only suffer a small defeat, instead of being steamrolled as it is in reality. Indeed, the Galaxy S6's display also proves far better in terms of color accuracy, with essentially every shade hitting its desired target at every intensity level, while the M9 falters significantly in comparison – reds are not quite red enough, yellows exhibit a greenish hue, and magenta leans heavily on blue. Further still, the S6 has and advantage in terms of maximum brightness and even gamma – 553 nits and 2.2 vs the still excellent 508 nits and 2.21 for the One M9.

The CIE 1931 xy color gamut chart represents the set (area) of colors that a display can reproduce, with the sRGB colorspace (the highlighted triangle) serving as reference. The chart also provides a visual representation of a display's color accuracy. The small squares across the boundaries of the triangle are the reference points for the various colors, while the small dots are the actual measurements. Ideally, each dot should be positioned on top of its respective square. The 'x: CIE31' and 'y: CIE31' values in the table below the chart indicate the position of each measurement on the chart. 'Y' shows the luminance (in nits) of each measured color, while 'Target Y' is the desired luminance level for that color. Finally, 'ΔE 2000' is the Delta E value of the measured color. Delta E values of below 2 are ideal.

This measurements are made using SpectraCal's CalMAN calibration software.

The Color accuracy chart gives an idea of how close a display's measured colors are to their referential values. The first line holds the measured (actual) colors, while the second line holds the reference (target) colors. The closer the actual colors are to the target ones, the better.

Interface and functionality

While the One M9's Sense 7.0 interface still is the fancier-looking of the two, Samsung has made incredible progress in terms of the smoothness of its own TouchWiz layout.

While Samsung's Galaxy S devices have always shipped with nothing less than the best available at the time in terms of hardware, we've often found ourselves wishing it did more on the software side. Its proprietary TouchWiz layout has often proved sluggish and less responsive than what some competitors had to offer – a sight that the Samsung faithful only tolerated because of the smorgasbord of extra features the platform gave them access to. With the Galaxy S6 edge, however, the company has finally seen sense, and has carried out a number of software optimizations that make the Galaxy S6 edge's software both easier to understand and faster than ever before.

Indeed, this is the first time that we can call the Android Lollipop-based TouchWiz experience truly smooth and hassle-free. But even though the company has cut down on the weight of its interface, the HTC One M9's refreshed Sense 7.0 UI is just as fast. What's more, and while we can't argue with people's differing tastes, we still find the brushwork of Sense 7.0 more appealing from where we're standing. The One M9, however, simply can't compete in the features department.

Quite right, the One M9's software reminds us a lot of stock Android, as HTC continues sticking to the basics and adds little on top. The interface looks differently, sure, but at its base is Android the way Google intended it. And while the updated, Lollipop-based Sense 7.0 layout brings goodies such as dynamic app folders that automatically switch their contents depending on whether you're working or at home, and can now be thoroughly skinned via the new Themes app (think icons, wallpapers, styling and ornamentation), it still doesn't compare to what Samsung offers.

With the new TouchWiz, Samsung is keeping a lot (but not all!) of the perks that made it unique, and refreshing or even completely re-designing areas that it wasn't completely satisfied with. For example, the S Health app has gone through a revamp and is now minimalist- and modern-looking while retaining the same wide array of functions. Like HTC, Samsung has also added support for third-party themes, and its own Themes app already offers a number of solutions, though none of them really caught our eye – for that, we'll have to wait and hope third-party devs feel incentivized enough to create something beautiful.

The Galaxy S6's stack of features is hardly exhausted yet, for we also have a new, improved fingerprint scanner (still embedded in the physical Home button) that is now of the touch, not swipe, type, finally allowing for a hassle-free unlock. Unlike the One M9, the S6 also offers software features like MultiWindow (run two apps simultaneously), Private and Car modes (hide sensitive content / dashboard with bigger icons and essential apps only). Finally, you were probably wondering if the display edges can be used for anything, and the answer is yes – they can show your notifications, and will also glow in a pre-specified color when your device is face-down and you get a call.

Processor and memory

While the Galaxy S6 edge's Exynos chipset proves a great alternative to the Snapdragon 810 in the One M9, it's Samsung's incredibly fast new storage solutions that gives it an edge over its competitor.

For the longest time, Samsung and Qualcomm worked together on the former's flagship lines, though the chip maker didn't always get all the orders – the rest went to Samsung's then fledgling semiconductor division making the Exynos chipsets. With the Galaxy S6 edge, however, Samsung was ready for a monumental shift, and Qualcomm is no longer part of the game. Instead, the S6 edge relies on a home-grown Exynos 7420.

The 7420 is an octa-core processor, built on a 14nm node, with two clusters made up by four cores arranged in a big.LITTLE configuration and Mali-T760 graphics. We have one group of power-efficient ARM Cortex-A53 CPUs, and another with powerful Cortex-A57 ones. The idea behind the arrangement is simple to understand – the efficient team of cores takes care of most trivial tasks, while the speedy A57 cores kick in when power is required. If maximum performance is what you need, the Exynos 7420 can switch all eight cores on and work them simultaneously.

Turning to the HTC One M9, we're seeing the chipset that Samsung deemed inferior to its own – the 20nm, octa-core Snapdragon 810. Qualcomm's latest available creation is quite similar to Samsung's, for it, too, offers the same four-by-four ARM Cortex-A53/A57 cores under a big.LITTLE config, the difference being the Adreno 430 GPU.

According to benchmarks, the Galaxy S6 edge has an edge in terms of processing power and memory, but falls behind the One M9 when graphics tests get involved. Indeed, the One M9's Adreno 430 GPU handles heavy loads in those scenarios better, achieving average frame rate values that are significantly higher than those of the Mali-T760. In general, however, using either of the two devices proves buttery smooth.

As for memory, we have 3 gigs of LPDDR4 RAM with both flagships, and a minimum of 32GB of internal storage. Speaking of the last, and we already touched on this, Samsung is utilizing what is without a doubt the fastest internal memory we've seen so far – a mix between eMMC 5.1 and UFS 2.0 – which offers vastly superior performance than anything we've seen to this date. That said, if you value storage expandability, the S6 edge will leave you hanging – for the first time ever, a Galaxy S line flagship comes without a microSD card slot, giving the advantage to the One M9, which does.

Internet and connectivity

All your needs will be met regardless of which way you go.

Smooth browsing is what we've been getting with each and every flagship for the past few years, and Samsung's and HTC's new offerings don't fail to deliver just that. Courtesy of their powerful internals, both devices handle even asset-heavy pages with ease and don't struggle when navigating through them. That said, whereas both devices rely on Chrome for your browsing needs, Samsung's Galaxy S6 edge comes with its own default solution that is an equally great performer.

Web browsing


On the connectivity front, you'll hardly find much to complain about, regardless of whether you go for the Galaxy S6 edge or the One M9. Both devices offer support for a wide array of LTE bands, 5GHz Wi-Fi, Bluetooth 4.1, NFC, DLNA, MHL 3.0 for streaming up to 4K resolution content to a secondary screen, an infrared blaster for control over home electronics, and even Miracast in the case of the S6 edge.

Where the Galaxy S6 edge pulls ahead is Samsung Pay – the company's new mobile payments solution that works hand-in-hand with the handset's NFC chip. The idea behind it is much alike to that of Apple Pay – the company gets retailers and banks involved (but free of charge), and you reap the benefit of never having to pull out your credit card out of your wallet again (much less physically sign any receipts).

Camera

HTC's supposed savior, the 20-megapixel camera of the One M9, is no match for what the Galaxy S6 edge has in store.

Samsung's Galaxy S line has always been synonymous with great camera quality, and the company wasn't about to drop the ball with the Galaxy S6 edge. Instead of focusing on the software side of performance, Samsung has taken a two-pronged approach by making sure to deliver some exciting hardware updates, too. To that end, the Galaxy S6 edge's 1/2.6”, 16-megapixel rear camera comes with a wider-than-before f/1.9 aperture lens and an optical stabilization gizmo attached to it. The selfie snapper, too, has received a commendable update, and now offers 5-megapixels of resolution and equally wide, f/1.9 aperture lens.

We have reasons for excitement when it comes to the HTC One M9, too, for the company has finally made the decision to ditch the 4-megapixel UltraPixel camera of old, which is now relegated to selfie service. At the back, we're now looking at a 1/2.4”, 20-megapixel sensor with relatively narrower f/2.2 lens and a dual LED flash.

Software-wise, we've got to say that we're witnessing a small miracle – HTC's, not Samsung's, camera app is the more feature-filled. We've got a ton of shooting modes, including panorama, night, HDR, and bokeh, not to mention numerous photo-editing goodies built right in. With the Galaxy S6 edge, we've got a re-designed, lighter camera interface that is easier on the eyes and snappier in its performance. The number of shooting modes has been brought down, too, but we still have the likest of panorama, HDR, Selective Focus, Virtual Shot, and a new Pro mode that gives you access to manual controls such as ISO, white balance, exposure correction, and focus. Another seemingly simple, but quite effective, feature – exactly the type we love – also can't be glossed over. More specifically, the Galaxy S6 edge's physical home button can now be pressed twice in order to almost instantaneously enter the camera, regardless of what you're doing at the time.

Camera interface of the HTC One M9


So let's talk image quality. Starting with daytime snaps taken outdoors, as with most high-end smartphone cameras, there's little to complain about. Both the One M9 and the Galaxy S6 edge produce very decent photos, and neither can be said to visibly outdo the other. They differ though. For example, the One M9 takes slightly brighter photos in general, much of that owed to a more aggressive ISO tweaking. On the other hand, the Galaxy S6 edge produces a bit more compelling-looking images, with warmer tones.

Indoors, however, we're looking at quite different a match-up. Unfortunately for HTC, the One M9's camera simply can't compare, as even before we have to point out the obvious color inaccuracies and far more severe noise levels inherent to the stills it produces, we have already called it a loss. That is for a reason – the software algorithms governing the camera push the shutter speed way low, likely in hopes of producing a sufficiently bright photo, but that comes at the terrible cost of blur – an issue the S6 edge does not suffer from.

The struggle is similarly one-sided when it comes to nighttime and low light performance. The Galaxy S6 edge fares considerably better, bringing us far brighter and more representative photos that offer more detail at the cost of much less noise. Indeed, in order to produce even barely passable night stills, the One M9 cranks up the ISO to 1600, and still fails to let us see much of the scene.

The One M9 gets no reprieve in terms of video, either, for its footage proves softer, less detailed, and a whole lot shakier than the Galaxy S6 edge's. That last part is obviously the work of the optical stabilization gizmo on board Samsung's flagship, as it does a splendid job compensating for trembles and shake in your hands.

In conclusion, we'd be remiss if we didn't make one thing perfectly clear: if camera performance is your number one priority, the Galaxy S6 edge is the clear choice between these two new flagships.



Multimedia

If you stellar audio is what you seek, the One M9 is the no-brainer choice here.

On the multimedia front, we have a few interesting developments. For starters, much like with the rest of the interface, Samsung has toned down the over-the-top rhetoric, and is now treating us to far cleaner visuals when it comes to essentials such as the Music player and the Gallery. In comparison, HTC's solution feels markedly premium, and we have to admit that we tend to like the brushwork better. Interestingly enough, this is another area in which Samsung's implementation proves slightly less feature-rich than HTC's – something we wouldn't dream of just two years ago.

Going back to music, if you happen to enjoy using your device as a portable speaker, then you'll enjoy what the One M9 has to offer more. Sure, we measured a slightly higher volume coming out of the S6's loudspeaker (75.4 dB vs 72.8 dB), but the difference is small enough to be nigh impossible for us to really tell. More importantly, the stereo front-facing blasters of the One M9 produce richer and more immersive tones, whereas the bottom-placed grill of the S6 lets out more subdued and thin sounds.

If you, instead, mostly use your smartphone with a pair headphones (as most people do), then it's even more clear-cut for you – the One M9 offers the astounding 1.022 Volts of power, while the Galaxy S6 proves a distant second, with just 0.53 Volts going through its 3.5mm jack.

Call quality


Samsung Galaxy S6 edge vs HTC One M9
One area in which HTC's flagship clearly surpasses the performance of Samsung's is call quality. The One M9's earpiece produces loud, clear tones, and the other side reported just as great results. With the Galaxy S6 we're looking at a more average showing, with audible, but hissy voices coming through the tiny speaker on top, and equally powerful, but thin voices heard on the other side.

The same can be said for the performance of the two loudspeakers – you can hold call with both, but while the Galaxy S6 mostly banks on being loud enough so that a call can be comfortably held, the One M9 tops that with both volume and better sound clarity.

Battery life


Like the microSD card, gone is also another trademark Samsung feature – the removable battery. This first in Samsung's book is owed to to the extremely thin body of the S6, and the sacrifices didn't stop there – the company also had to go with a relatively small, 2,600 mAh battery. The HTC One M9, too, doesn't allow users to meddle with the cell, but the one embedded within has a slightly higher capacity at 2,840 mAh.

In reality, these capacities translate into battery endurance in a way you wouldn't expect, especially since the M9 has a bigger battery and a far less pixel-dense display. Indeed, while the Galaxy S6 manages the very decent 8 hours and 11 minutes on our custom battery life test, the One M9 is average at best, with a score of just 6 hours and 25 minutes. Still, do keep in mind that all devices that go through our battery life test are set to 200 nits of brightness, which was impossible with the Galaxy S6 edge – manually, the most you can set it to is 180 nits. In other words, the S6 edge went through our test with a slightly dimmer display than the rest.

Conclusion


If you've ever struggled picking between two great flagships in the past, you'll likely know what we ourselves understand all too well – when you're looking to make the most out of your hard-earned cash, choosing can be difficult. Fortunately, with the Samsung Galaxy S6 edge and the HTC One M9, things are clear-cut enough for you to simply have to identify what's important to you personally – the answer will come to you by itself.

So, do you value camera performance and battery life above all else? The Galaxy S6 edge, then, is the obvious choice – it steamrolls the One M9's unsatisfying, 20-megapixel shooter, and manages almost an hour longer on our battery life test. It also has the slightly larger display, which is notably superior to its competitor's solution when set to 'Basic' mode.

Are you more intrigued by the design work that goes into your gadget? Is sound quality an overly important consideration for you? And are you annoyed by software gimmicks? If you mentally noted a 'yes' whilst going through those three questions, then your choice is fairly straightforward, and its name is HTC One M9. Indeed, while Samsung has spent considerably amount of effort trying to classy up the Galaxy S6 edge, and we sure dig the futuristic-looking display, the M9's full aluminum unibody is uncompromisingly beautiful, and comes with none of the oily mess that is the S6 edge's back. What's more, the One M9 is a far superior platform for listening to music – whether you go wired or not.

Ultimately, point-for-point, the Galaxy S6 edge is the superior device of the two. But it's not the classier – a subtle, but important difference.
