I've owned a few...starting back around 1980...and they're all pretty good. I shy away from the Polaris name because they are murder to work on and I've had more problems with them.
The best bike I've ever owned is the one I currently own and that's a 2003 Bombardier Quest 650. They're not made anymore...but Can-Am who bought them is still making a good bike.
Ride a few and pick which one feels best.
