I have never ridden one, but I think they (the DVX) are good looking machines. Their DVX is the genetic twin to the Z-400 Suzuki, and I owned one of those and LOVED it. The advantage the DVX has is the front fenders are removable, so you don't have to go thru the process of shaving them off if you like the no-fender look. So, essentially, I have ridden a DVX and can tell you if you are looking for a great trail and occasional track quad, and like sport quads, I'd highly recommend it.
I haven't ridden the utility quads, but I'm not too crazy about the look of those vs. the DVX. They are big, that's for sure, but based on everything I have read in the quad mags they usually rank near the bottom in class shootouts. The one area they seem to have an advantage is in ground clearance. Seems you get that extra 1-2" with a Cat that can be helpful out on the trail. Most magazine testers complained about mechanical problems such as fluid leaks and weird electrical glitches. Don't get me wrong, I'm sure that there are LARGE amounts of Cat riders out there who are running trouble-free machines, but it seems every time I read a test of a Cat utility quad, the ratings are pretty low.
It seems Can-Am usually scores top numbers in power and accleration, but the Grizzly 700 with power steering seems to be the magazine favorite............this year.
I am anxiously awaiting the newer mid-size utility shootout (400-500cc) just to see how my KingQuad will stack up against the competition in the professional's eyes.
