If your getting a 4x4 I highly recommend the brute force, they're light very powerful, handle pretty good and I haven't had any problems with mine and I'm on the throttle and ride hard most of the time lol
Trailboss.. The trailblazer is the sportier 2x4 one.
The older polaris are better then the new ones imo.. The newer ones are made cheap..
Nothin is more reliable then a jap bike so I say go for the trade lol
