It's really personal preferrence.
Supercharger is run off a belt connected to your engine. It takes engine power to turn the blower to create more power. This is known as parasitic power gains.
Turbo uses the exhaust gas to spool, so every hp it makes is pure gain.
Both are built to handle a variety of power bands, but generally, a blower will give you more low end, and a turbo will give you better gains at higher rpms.
There are some super chargers that work more towards higher end gains which are used in drag racing along with turbos, but most street superchargers are for gains from just above idle.
