No intent to get into a pissing war over turbos or superchargers..... but from my perspective... a good turbo or two is a better choice for the long term than a supercharger, for a variety of reasons.
I wish you luck whatever your choice... but I don't know anyone who has had a supercharger... that liked it once the novelty wore off and the repair and maintenance bills came in. On the other hand.... I know several people with turbo cars, myself included, that are more than happy with turbo performance AND longevity. My current turbo car (non-chevy) has 93000+ miles on it... never been taken apart or rebuilt, and still turns mid to high 12's in the quarter just as it did when it had 35000 miles on it.
I can't speak highly enough of a well put together and tuned turbo system, as a machinist and engine builder.
