I have a black 4S, and preferred it over the white, obviously, But when I went to go see the 5, I liked it better in white. The color you choose is relative to what appeals to you. I don't think anybody can convince you which color to get.
The black was nice, but the contrast of the gunmetal steel against the black was different. The white, on the other hand, had an appealing contrast which blended perfectly.
Oh and this!!!!Love the shiny edges.
A poll would be a good idea on this thread.
