I tend to agree with you MacJunkie....

TCs are great for overall power, higher power potential, and on the fly boost adjustability, but their drawback is heat and complexity.
SCs are great for simplicity, instant responsiveness, and a little less weight than a turbo. There is also no lag or boost threshold because boost is always there, so the engine feels more linear/predictable at partial throttle and on/off throttle. SC drawback is mainly less adjustability on the fly.
Twin screw style SCs squish air into the engine by physical compression, they offer the biggest gains at low/mid RPM. Centrifugal SCs use an impeller like a turbo, so they're very efficient, but the power curve rises linearly with RPM so they are most effective at high RPM.

Nice, informative post, some good points.
I don't like the idea of parasitic loss due to a SC...there is something about a turbo and the way that it uses exhaust gasses (that would otherwise simply be expelled) to make more power. I also like the idea of being able to drive out of boost, hence turbos generally being able to get better fuel consumption then SC's.
Depending on the kit you choose and the precautions you take, heat issues can be minimized with turbo setups as well.
Each to their own however, thanks to all for the input.
