Point of forced induction is you want power when you push the pedal......turbo's must spool boost....supercharger's are automatically there.

New hybrid turbos have damn near no lag. and unless you're going with a big roots style charger you dont hear much noise. The newer twin screws just don't make that much noise and centrifugal charges are pretty quiet too.... the twin screw of the mustang cobra can barely be heard over the exhaust.

The spool with a turbo is kind of cool, at least on a street car. Sleeper. See a car take off slow, think nothing, then hear that jet sound and its gone.

the stock supercharges on the cobras are very easy to hear.
ive never driven anything with a quiet supercharger. roots, centrifugal, twin screw all all pretty easy to hear.
in my mustang, and even with my old GTP with a little m90 you never had any issues hearing the superchargers inside and out.

For a pushrod style engine like ours that only spins out to 5,000 rpm a supercharger is ideal because you can "tune"(change the pulley size) to make a significant amount of boost right off idle, while not over exerting and damaging the super charger at redline. It'd be very difficult to get that from a typical turbo setup because there's just not enough exhaust flow to make usable boost off idle and still be able to run all the way through the powerband.
That being said, if you got ambitious you could always build a compound turbo setup.
For a Jeep though, a super charger is much simpler/easier to set up, and get tuned right compared to a compound turbo. Plus if you wheel your Jeep and there's ever any chance of being in deep water or having water splash up in the engine bay, the last thing you want is to dunk/soak a turbo in water.

Oooh didn't think about submersion. That would hurt! Although I'd I put that much $$ into my engine id probably stay away from creeks and small rivers anyhow unless I knew exactly how deep they were.

buy two kits, 200$ and it'll cover your whole jeep, and then some. I did almost my whole jeep with 3 bottles
