this is killing me trying to figure out what to get iam sure they both are good machines this being my first quad either one will be awsome

 

Get the Grizzly 450 and you wont regret it. It doesn't have all that electric steering stuff. I feel more control with manuel. That is orginaly how they have been made. If you are a begginer as i was i just bought the 450 and i have no regrets it is the BEST ATV MADE EVER. If you were using it for farm work and carrying and pulling trailors nonstop then i would say get the 700 or 660 but if you are out there for the fun and still it has low and high gears which means when i put a ball hitch on mine it pulled anything in low. when i pulled a friend out of a mud pit i used low and those wheels won't stop moving. THE POWER IS AMAZING ON THE 450. "2007 Grizzly 450"
