In this regard, turbos can lead to lazy shifting, and superchargers require downshifting to get into bigger boost numbers, but when that happens the boost is instant, where downshifting in a turbocharged car will still have some lag, even with a small turbo.

Unless you keep your charge pipes pressurized between shifts like I do... or run some sort of anti-lag.
