It depends on what you would be using the machine for. IMO they are basically the same machine so if you don't like one the other won't satisfy you either. Size, power and speed they are going to be pretty close. Looks and suspension are going to be different (plus a lot of other things, some good some not). I'm interested in the 4 seat for one reason only, giving the kids a ride yet not a long machine when I would be out by my self. I can't wait to drive a Pioneer and see if there is much of an improvement over the Big Red, if any.
