a 450 is a 450
IMO they are all about the same
they r meant 2 be kind of stiff and set up 4 the track so if u want something more versatile, definitely get the 700
i have a LTR450 and my dad has a Raptor 700
my 450 is a bit more exciting, but the 700 rides like a Cadillac and it can stay up there with my 450
