I don't think either one is technically "better" then the other. It all depends on what you want.

A turbo is going to have greater power potential as it is easy to turn up the boost and there are tons of aftermarket parts on hand to upgrade a turbo system.

A supercharger can be modified, but your options are limited.

A turbo is going to have some lag, where a supercharger is going to give you off the line boost.

I prefer a turbo, but some prefer a supercharger.

If you want an all out street beast defenately go with a turbo.
