For superchargers, you're stuck. Whatever pulley you have in there will determine the boost pressure. You cannot change boost levels easily. And I'm pretty sure given the same horsepower and boost level, a supercharged car will generate more heat. In a supercharged car, a significant portion of horsepower (and hence heat) is wasted on spinning the supercharger. Whereas a turbo uses mostly exhaust waste to spin. This is the same reason the superchargers use a 650cc injector to make similar or less horsepower than a turboed car, which is using a 600cc injector.
