The new HTC One M8 was one of the most leaked devices in recent memory, but that didn't stop it from absolutely flooring us with its gorgeous new unibody design.

It's not a huge departure from last year's One, though, instead offering incremental refinements that make it feel more luxurious than ever. Sound like a familiar formula? Yes, that's been Apple's M.O. for years now, and has worked with aplomb if you judge by the success of the iPhone 5S. It's only fitting, then, that we compare these two design titans to see the differences between them, and how they stack up.

The iPhone 5S and the One M8 are easily the two best-looking devices on the market right now. And it's not just outward appearances – both of these devices share that airtight build quality that evokes awe and wonder. If you've been following along at all, you should already know that the One is nearly an inch taller, a half-inch wider, and over 50 per cent heavier than the iPhone 5S. Fans of big-screen phones probably won't bat an eyelid, but if you're looking for a device that's comfortable to use with one hand, the One is probably not for you.

That big body accommodates the 5in 1080p LCD that truly dwarfs the iPhone 5S' 4in display. HTC's panel is sharper, too, packing in 441 pixels per inch to the iPhone 5S' 326 ppi. All that extra room also helps fit in HTC's unrivalled front-facing BoomSound speakers. They're easily the loudest and best sounding speakers on any smartphone.

The big, sharp screen and outrageously loud speakers make the new One a media powerhouse. If you're planning on using your phone for your next Netflix binge, it's hard to argue with HTC's new flagship.

It's more difficult to compare performance between these two devices, as Android and iOS are completely different ecosystems. Both of these phones absolutely fly, though, so you shouldn't have any concerns there.

One of the biggest differences will be the cameras on either device. HTC stuck with its 4-megapixel – or Ultrapixel – sensor, which wasn't exactly an industry leader even last year. The new depth-sensing Duo Camera lets you add Lytro-like refocusing ability to your pics, but quality still isn't top-notch, from what we've seen. The iPhone 5S still produces more consistency with its 8-megapixel camera. But that's just rear-facing imaging – once you turn the digital eye on yourself, HTC pulls way ahead. The 5-megapixel front-facing camera on the One M8 is the best for selfies hands-down.

Beyond that, there are a few unique features to each device. HTC has its IR-blaster while Apple has its Touch ID fingerprint scanner. The One also comes equipped with a microSD card slot, so you can add even more internal storage for a fraction of the price that Apple charges for its upper-tier 5S models with plentiful storage.

These two devices trade blows when it comes to design, but as for comparing Android to Apple, well, I'll just leave that up to you. Have a strong opinion? Let us know which device you think reigns supreme in the comments.
