From pure color preference, I prefer black. But I chose to have white iPhone and iPad because it's just more practical color for me - black bezels just SCREAM, "look at all the smudges on me, look at all these thick bodily oils and germs!!!" On white bezels, you can't see smudges AT ALL. Same with car color: I chose white as more practical - less heating in the sun and dust is less visible, the car looks cleaner overall (black car looks nice only for a few minutes after the car wash, then you can see every speck of dust on it).
