The Raptor has reverse which the other 2 you listed do not.
Secondly the 450 class machines like to be revved & make good power when doing so, however they are lacking low-end torque/grunt. Something the Raptor has no trouble with as it has gobs of low-end torque due to its large displacement, good for tight/slow woods riding.
If you want something for the trails get the Raptor if your looking to take it to the track every weekend get one of the 450's instead.
All three have more than enough aftermarket support, to satify anyone.
