Some superchargers provide linear boost, others behave much like a turbo. In any casem FI is used to increase efficiency, so it doesn't make sense to use a super charger with a must larger parasitic loss. Modern turbo can provide boost from 1500 rpm, and result in a flat torque curve - the only negative thing is the lag.
