If u r going to autocross/gymkhana/slalom/HPDEs, maybe a track day here or there, then the Z06 is ur Corvette.
But if u r planning is none of these, maybe just to cruise around, take trip to/from the NCM, maybe participate in one of the NCMs MiM events, or KY 1 Lap, etc, etc, then the Grand Sport is ur Corvette.
No comparison of the suspension systems of both in the above analysis, but it is well known the Z06 is stiffer for more competitive driving.
The choice is up to ur intended use.
