I think all the machines these days are pretty darn good. I have had Yamaha for 12 years (originally a '97 Kodiak 400 and just bought a 2009 Grizzly 550 EPS). I think they are the top of the line. If you compare specs overall I think they com out on top in most. I really like the new Grizzlies. Great looking, power steering, tight turn radius, awesome transmission, great clearance, and they ride great. My only real complaint is the racks are rather small (compared to my Kodiak) & sit tight to the body which makes carrying & bungying gear a bit tricky.

I would say figure out what you want/need (where you riding, what are you doing with it, engine size, etc.) and take a good look at alll models, and talk with sales folks and reps. Compare the key features, ride the few you narrow it down to, and make a decision after taking it all into account.
