ok this is a stupid argument. if you want to trail ride/drag race go with the 660. if you want a good mx quad go with the 450. and no the 450s will not beat a raptor in a drag race (built vs. built) unless there are turns involved.
450 if you want handling, raptor if you want brute power. i think that overall the 450 comes out of the factory a better machine but with a few modifications the raptor can be just as good if not better. but in reality the were not made for the same reasons so you can compare
