In my experience, the turbo setup will not be as smooth or consistent as a supercharger setup. The thing about a turbo is that it is not directly mechanically regulated, so once that turbo starts to spin, the impeller speed increases exponentially, whereas a supercharger will have a linear increase in impeller speed. Turbos can produce more power per RPM than superchargers, but at the same time keeping a turbo under control is not as exact as having a supercharger that can only spin as fast as the engine allows it to. Turbos can have things like boost spikes and overboost, which are not generally problems with superchargers. Either way forced induction rocks.
