Preference
My preference would be a KB, but between the two you list, the ProCharger gets my nod. I like the internal lube system which does not rely on sucking hot oil from the crankcase.
As for supporting cast, that all depends on the situation. I would recommend you spend the money on the ProCharger's upgraded intercooler, which will give you a more solid unit with more boost potential.
