I agree about the fun factor but if you want to go fast a SuperCharger will typically beat a Turbo any day except in price.
Also just to add a little on the explanation of the two... A super charger is typically belt driven off the crank shaft like the Alternator is. It cranks a compressor that compresses the incoming air into the intake of the car. A turbo does a very similar thing but instead of being ran off the crank shaft it is is propelled by exhaust gases. You basically have to fan blades. One is in the exhaust being pushed by the exhaust. The other fan is in the intake of the car but the intake has to be ran down low in the car near the exhaust so the fan can be put in it. Compressing air causes it to heat up and expand which in turn defeats the purpose of getting more oxygen in the motor. So what you do is run the compressed air through what is called an intercooler (not all turbo or supercharged cars have them). An intercooler is basically a big radiator that the compressed air goes through prior to entering the intake. It is more common to run an intercooler on a turbo then a supercharge simple because turbos heat the incoming air more due to there proximity to the exhaust.
