Boost is adjustable. You can't change NA output as drastically with the turn of a knob like you can with forced induction. This is a huge advantage during a race. If FI was best... all engines would have it (sorry Moe).
If reliability was the only factor we would all drive single cylinder engines. Fewer parts. Both Occam and Murphy agree on this point. (What the hell do they know about motors anyway?). My $0.02
