Idk dude, that blue one looks classy as f*ck! I say, get the blue one. It stands out. Blue is the color of royalty, too.
Blue = Classy, gentlemanly, of nobility.
Black = boring, drab, peasant-like.
Jk, your decision. I'd get blue, though. ;)
It'll be awhile before I figure out how to do one of these. :P
