They had this to say:
I don’t like holding this phone, and I can’t overstate how much that informs the experience of using it. It makes an awful first impression, slippery and slimy and simply unpleasant in your hand. My white review unit is completely smooth and glossy, with a subtle checkered pattern that looks textured but is neither grippy nor textured anywhere on its body. Even the silver band around the sides, which is obviously supposed to look like metal, is plastic. Everyone I showed the GS4 to frowned and wrinkled their nose as if it smelled bad, before rubbing their fingers on the back of the phone and then handing it back to me — that’s the opposite of the standard reaction to HTC’s One, which everyone wants to ogle and hold.
The Galaxy S4 is fast and impressive, but it’s also noisy and complex. The One is refined, quiet, comfortable, beautiful, and above all simply pleasant. I love using that phone, in a way I haven’t experienced with anything since the iPhone 5. That’s why, when my contract is up in June, I’ll probably be casting my lot with HTC instead of Samsung.
Other than that, it’s great!
