Depends on the type of supercharger.

Centrifugals tend to have less low rev torque but make good power at the top (compared to roots and twin scroll variants) and generate less heat than a turbo does. Centrifugals also make a f*cking annoying noise at idle

I also find that supercharger 'kits' are more readily available taking away a lot of the custom work

Also remember it's about driveability too rather than outright power.
