Myself, unlike very many, like the supercharger better. For one, it's a simpler setup. Also, in my opinon, alot safer too. The reason being, your just throwing more air into the chamber, rather than using expelled hot air to get power. As far as reliability, it all depends on how well the setup is done and taken care of. With a supercharger, initial setup is very easy and it would be hard to do something wrong. (Just remember to add a FPR so you don't detonate the head). With a turbo, not only are there so many parts, but you have to tune it out in many different aspects for it to run proper. Plus, there are some added "care" bonuses that tag along with turbo (as far as reliability and longevity goes). For example, it would be smart to let the engine idle for a couple minutes before turning off the motor so you dont get dry spin (no oil being sprayed on turbine). Also, with turbos oil changes are recommended alot more often than stock.
As far as power:
Turbo = hella more hp/tq for the sheer fact that you can keep adding psi. I suggest running no higher than 7 psi on a stock motor. Anything higher will put more stress on the motor than isn't necessary. So, if you go turbo for hp/tq, the output will be roughly the same if running comparable psi to the supercharger. If you are looking for mad power like some turbo equiped imprts have, expect to spend hella money for internals just so you can crank that psi up a couple points.
Supercharger = As said previously, the output would generally be the same as a turbo, give or take 10hp. Plus, the supercharger is ON-TAP. That means as soon as you give the system some gas, its already forcing massive air into the combustion chamber. True, it runs off a pulley system, but that is it (besides the supercharger and belt). No need for worrying about cooling system, overheating, or drilling (creating) oil feeds.
In the end, if you are willing to spend a bundle on an FI system, and have good tuning skills or are taking it to a shop that has precise tuning skills, I would highly recommend a turbo. Also, you must be willing to deal with those extra bonuses we discussed. One last thing, with a turbo you have the option of selecting a turbo size which means you can get incredible power in low rpms (spooled by 1500rpm) go midsize and have turbo power midrange, or sacrifice your bottom end for that blistering top end turbo power.
If you want a FI system that is incredibly reliable and will last you a very long time with practically no extra maintenance needed than supercharger is the way to go. Great for street (stop light to stoplight) racing. Easily installable by yourself with basic tools and an instruction manual.
It just depends on what your goals are and what your willing to do or pay for them.
Ugh
