We put 2000-2500 miles per year on the 2 UTV's we have. It's 100% in the field use and much of that use is at times when a vehicle (Jeep or otherwise) would leave horrendous ruts or simply get stuck. In MO, we don't pay sales tax or registration on UTV's for farm use. Our UTV's aren't for trail riding and playing, they're tools or implements so our views of comfort may/will be different. Even the noisiest, most uncomfortable UTV beats the heck out of walking. Polaris takes a beating and keeps working but that comes at a cost. They're expensive(new or used), they have some quirks and weak points, and the factory accessories are VERY expensive. On the other hand, there's a plethora of aftermarket parts and upgrades at very reasonable prices.
If the OP is simply looking for something to enjoy riding around here and there, one of the smaller, more basic units such as the 570CC Polaris would likely be both adequate and lower cost. If buying a used one of these, be cautious as the cooling on the smaller CC units is not as foolproof and a previous owner may have run the engine VERY hot at times.
