Depends a bit on your definition of 'works better' ... but a turbocharger
(which strictly speaking is a form of supercharger) works better in almost
every way except throttle response.  More power output and better efficiency
for any given altitude, engine and fuel; naturally adaptive to some extent;
and easier to control to provide adequate boost at altitude without
overboosting at sea level.
