Definitely go for what ever you think is best for your personal situation.
You should also remember a turbo does not hit the engine as hard on the bottom but hits it much harder on the top and of course you can't hear incipient detonation at lower engine speeds so you definitely can not hear it at higher speeds.

You probably want to read that article spdbrake just posted and click on the Hennessey's 800 hp Venom 800. 12:1 compression and they are running 8 psi of boost with a supercharger. Do a bit more digging and you will see they are plopping superchargers on the GT350 with a flat plane crank and 12:1. The days of running 8:1 CR on a supercharger engine are pretty much past history unless you are building a 1960's engine.
