I have a 17 Grand Sport A8, and a 22 Zl1 A10. Both great cars.
Drove a Z06 before buying the GS new in 2017. Can no longer drive manuals due to hip and knee issues.
If I could only have one, from a strictly driving perspective, it would be the Camaro. The Corvette does have an aura about it, and is a great all-around package, but the ZL1 is also more roomy (upfront), has better seats, is super quick, handles great, and is a spectacular package in it's own right.
And for perspective, I recently got this, but have not yet finalized my opinion.
