I think I've ridden most of them. Polaris is my preference. I like the power and especially the suspension. The Can-Am has nice power, but I liked the Polaris suspension better.
If you're only using it in the pastures, all of them should be good enough. I liked the Honda for ranch work, but didn't care for it on trails.
Stay away from the real cheap Korean models. Engine trouble and soft suspensions are common with them. Not to mention, finding parts or someone to work on them. My step-dad has one (and a Polaris) and I told my daughters they're not allowed on the Korean thing. It feels like it will roll if not ridden very safely.
