The biggest benefit IMO is the amount of power turbos make vs blowers size for size. It's seems blower guys are always chasing their tails trying to keep that belt from slipping when they get up in the higher boost levels. Turbo guys have to deal with the amount of room that's needed for all the plumbing. To me turbos seem to be more technical with the correct size plumbing, intercoolers, BOV, waste gates, AR, etc... Superchargers are usually just a bolt on kit with little plumbing.
