Expanding on what you said about looks, I really love the Mustang from most all angles. I think it has a very classic and sexy shape, sort of like the Z does. Looks elegant in many ways.
The Camaro on the other hand is a total brute... sharp lines and creases chiseled from a brick basically. I love the front and front-quarter view, but am not a huge fan of the side profile or rear view.
I think the Camaro looks brilliant from this angle:

Or this:
I still really like it, though... Sometimes I wish I was diehard Ford or Chevy so I could just dismiss one or the other and not have to make any tough decisions.
