i like both B&W and OEM.
OEM is good no matter what.
I also prefer clean B&W badge on a blue car. Something about the light blue color of the badge clashing with say Montego or Lemans a bit. Just gets a little busy. In that case I like the B&W.
Don't like CF badges as the weave always looks too big for the size of the badge. Kinda same effect as those monster sized POLO logos on polo shirts. Just don't like it.
For super aggressive all blacked out cars though, I think this is perfect too (and so fking evil!):
