I have the 450 ES, but I think it is awesome. The foreman has alot of power. I am a pretty big guy, about 265 pounds. The foreman takes me through all kinds of stuff. I have 27" swamplights with a 2" lift. I actually was considering the Gators but I got a good deal on the swamplights. I can't compare between the 450 and Fourtrax, but I would say I would like a little bit lower 1st gear on mine. My Foreman, at the time of purchase, ran at 55 mph stock. Now it won't do but about 47 mpg, probably the mud tires. My opinion is to get an aftermarket exhaust. I believe the factory exhaust is to restricted. I noticed alot more power when I put my HMF muffler on.
