I have the black 3DS. I think it looks pretty cool, and it was definitely the best color available at launch, in my opinion. I haven't seen the new color variations that have materialized since then, though, so I can't really speak on those. Also, I have the green OoT cover that Atticus mentioned; it looks nice, and suprisingly doesn't make the 3DS feel too bulky - though perhaps that can be attributed to my large hands. :bleh:
