The short version:
Two main types for cars. Procharger, Vortech, Paxton all use a centrifugal type supercharger. They are very similar to a turbo, however instead of being exhaust driven, they are driven off the crankshaft. Boost pressure is linear, and follows engine RPM. The higher you rev, the more boost you make.
Positive displacement/Roots - Magnuson, Eaton , Edlebrock , etc. These use rotors/screws to compress the air. They are also driven by the crank, but the difference is they actually put out a significant amount of airflow and boost at low RPM.
The long version -

So, what would people want for their V-6? Positive displacement, or Centrifugal? Turbo? The varieties of people, the varieties of choices, again all have to make sense when you are looking at a product like forced induction.
