My side X side is a full size Ranger, a full cab, hard doors and a real glass windshield, it rides good. Since there has been no ATV/UTV dealers within 100 miles of me and a Can-Am dealer just came to the area this spring, I will probably be thinking of one of them the next time since they are close. Personally I don't want to have to deal with shifting, much more convenient not too. I have had 4-wheelers and 6-wheelers over the years and have never had any belt problems, even on the 6-wheelers we worked hard in the mud in our field drainage business, maybe I have been lucky, but the times I have been in deep slush with the Ranger, the belt was not an issue (it is lifted an extra 3'" for rock/stump clearance), snowmobiles and belts are an entirely different issue.
Not knowing how you will use the UTV, there are a few things you might consider. If you are getting a full cab, windshield wipers are a must, electric windows are really nice, a heater is a plus, if you get in bad stuff a rear winch can be useful, do not consider anything other than rope winches.
I think the name brands will all be good, but would stay away from the Chinese ones, I would say that the Kawasaki Mule is the worst riding UTV I have ever been in, would never consider one simply because of that.
