[CLEAN]

I've got both, and I LOVE the G8 GT. It does a lot of things better than the Camaro, but it has a few quirks that take some getting used to. I'd say the things that I prefer in the G8 over the Camaro are

Practicality when hauling the family
Visibility
Tranny programming
Invisible AFM, in the Camaro, it feels like another gear when it kicks on and off!
Smoothness

Handling and Braking are VERY close, the edge probably going to the Camaro.

Camaro is good for

Looks
Speed

Good luck w/ your decision!
