I actually went back to black after owning the white/silver. I just think this one will look slick. Plus, I plan on getting the Product Red case. That will look pretty awesome.
Got silver 5s. Sticking with silver for the 6+. Was never a fan of the gold, and I think the gold one looks even worse with the white antenna band. The space grey does look better on the 6/6+ than 5s now with the lighter shade.
