Oh boy... be ready for the "Use the Search" assault...
I think it is safe to say that the GTM kit is more used and respected HOWEVER a few folks have had great success with the Stillen kit... notably RCZ.
GTM uses the Rotrex kit which, in my opinion, has more potential than the other centrifugal and roots style kits.
There is an interesting read regarding someone who switched from Stillen to GTM floating around and I think their opinions are valuable considering they experienced both.
And one more thing... tuning, tuning, tuning!
