for the cash you spend on a vortech you could have like a stage 2-3 SFP kit. Vortech superchargers are more high high end HP and not all that linear. Superchargers are also going to make your under hood temperatures higher then a turbo especially the JRSC. Detonation management is not going to be much different when speaking in terms of the amount of boost your running. I personally like the expandability of the turbos myself. My car isnt going to be a drag car thats why im going to boost qabout 4psi for daily driving and then flip the boost controller over 2 settings for 9-10psi for racing.
