With Samsung's Unpacked event well behind us and HTC's One successor officially unveiled, the stage is set for yet another heavyweight Android showdown.

These two companies have been duking it out for Android supremacy for years now, and this year's battle once again pits Samsung's feature-packing might against HTC's design chops. Faster performance, bigger screens, and bold new features are all table stakes at this point. So how do the Galaxy S5 and HTC One M8 stack up? That's what we're discussing here...

Last year's Galaxy S4 and HTC One were both incredible devices that showcased the best features and designs that the mobile world had to offer. Truth be told, not a ton has changed in the past year. Both the Galaxy S5 and new HTC One M8 draw heavily from last year's models in terms of design and features. The Galaxy S5 is slightly larger than its predecessor and trades glossy sheen for a dimpled texture, but it's still a typical, all-plastic Samsung device. The One M8 is also bigger than last year's model, but ramps up the high-end feel, cutting out as much plastic as possible for its new aluminium unibody design.

HTC steps up its display size, from 4.7in to the increasingly standard 5in mark, while Samsung adds 0.1in, bringing its display size up to 5.1in. Both panels boast a 1080p resolution, with HTC sticking to LCD technology, while Samsung continues with its AMOLED designs. Samsung also showed off some new battery-saving tricks that take advantage of AMOLED's ability to turn on individual pixels.

Both smartphones will utilise Qualcomm Snapdragon 801 chipsets, which offer a step up over current Snapdragon 800-powered devices like the LG G2. Blazing-fast performance and high-end gaming chops are a given, while battery efficiency should be improved over last year's models. HTC says the improved power saving mode that comes with its Sense 6 UI can extend battery life by up to 40 per cent – a bold assertion that certainly needs to be tested.

The foundations underpinning both devices are largely comparable from a spec-by-spec standpoint. The real area of differentiation is in the added features. Samsung has a few tricks up its sleeve, including a case-less waterproof design and new sensors for security and fitness tracking. A fingerprint scanner built into the Home button apes Apple's last release, while a heart-rate monitor embedded in the back will be a boon for fitness nuts.

HTC's banking on some clever new camera tech to once again set its One apart. Last year we saw the debut of the "Ultrapixel," which makes a return this year, but now with a new Duo camera sensor that adds new features like the ability to refocus images after you've taken them. The new One is also packing a 5-megapixel front-facing camera for what should amount to some high-quality selfies.

We're still testing both of these devices, so stay tuned for full reviews and a definitive answer as to who takes this year's Android supremacy crown. In the meantime, at the moment it seems a close run race, with perhaps those bells and whistles making the difference. Which device has you itching to upgrade? Let us know in the comments.
