And I heard that they're more efficient...meaning it doesn't take time spool like the turbo does.... Dont be afraid to elaborate.....I just want to educate myself a little on the subject.

The adiabatic effieciency is worse meaning that if you figure out what the heating should be from just compressing the air via the ideal gas law, pv=nrt and what it acutaly is from the compressor, the turbo is more efficient and heats the air less while compressing it.
A roots supercharger is about 50-60% efficient and a centrifugal is around 60-70%.
A good turbo is from around 75-80%.
It equates to less charge heating, less work needed to compress the air with a turbo.
