I think the Camaro looks much better...

By the way, the Challenger is HUGE! I don't know if it's just because it's a show car...you think they'll shrink it down before production? Seriously, it's the size of a 300. Makes sense, since they run on the same platform...but that's way too big for such a car. Also, the Challenger looks sort of bloated...not very well proportioned.

I think the Camaro looks a lot more aggressive. Problem is...I think, as a show car...it's proportioned perfectly. For the production model though, I know they're going to have to change a few things up to meet some standards. The roof might be too low, for example...but that makes the car look so sleek. I think the only thing they need to do is fix that grille...it looks like the car has braces.
