The effect of both is the same building boost higher then that of the atmospheric pressure entering the engine. The method of producing the power is different with a turbo your not sacrificing power to make power; however your increasing engine bay temps (in some instances depending on the amount of boost you actually increase the efficiency of your engine) But with superchargers your creating boost by running off the crank pulley and anything that runs off your crank pulley will rob your engine of power (not really a significant amount though) and with a supercharger there is less heat created by the boosted air allowing you more lenience with intercoolers and such this is why superchargers are used in carbureted applications for drag racing being less chance to percolate the fuel in the carburetor which is basically the same as detonation in a fuel injected car.

Wow your summary is inaccurate sir. Superchargers have a greater tendency to heat soak because their cooling is essentially limited to heatsink style cooling. Some superchargers have aftercoolers but with increasing heat for the blower decreases the efficiency of the supercharger AND it blows hotter air into the intake manifold. On the other hand increased temps on the turbo especially on the turbine side increases the efficiency of the turbo. If anything superchargers have a higher tendency of detonation duel to the fact that they can't really cool the air going in to the engine properly.
If you want to talk advantages of the using a blower you could have mentioned that blowers are less likely to fail due to the fact that you dont have oil lines and or waterlines to maintain. That in my mind is the only true advantage of a superchargers over a turbocharger.
You like blowers. I get it, but don't post inaccurate information. There is a reason why most car manufacturers now use turbochargers instead of a supercharger in vehicles.
