Between turbo and supercharger, I'd go with supercharger.
First, it's more efficient and quicker. The turbo has to have a certain exhaust flow before it really kicks in and loses some power since it restricts the exhaust a little. The supercharger winds up faster since it's belt driven and does not restrict the exhaust at all.
Second, the supercharger takes up less room. The turbo is harder to fit and takes more effort to install.
The plus for the turbo is when it winds up, it sounds cooler.
