STS turbo vs. roush supercharger

[NITEMARE07]

I've done some research on sts turbo systems and roush chargers. Previously i always thought hands down superchargers are the way to go. But upon researching the sts turbo systems many guys swear by them and some even say that they will never go back to superchargers. Now i know depending on what setup i would go with determines the output as far as turbos are concerned. So lets say for example i have a 8lb boost turbo with tuned computer. How does that compare with a roush charger with tuned computer. Keep in mind it will be on a 5.4L 4×4 4 door. Just testing the waters so to speak on this topic.
