I have the black one and i like the color i use it with a matte screen protector so no fingerprint problem on the front side and the back cover is not like a glossy black so both sides no problem.
I also like the white one but the aluminium frame is grey (as you would expect but not the glossy aluminium grey) as in the black one the frame is painted black like the rest of the phone giving it a smoother look.
I like my choice and i would recommend the black one but watch out if the frame paint gets damaged by a fall it will look awful.
That's what i think thank you .
