There are probably more variations of wheeled and tracked vehicles in this country than any where else.
Although I have never owned one I have used a few and this is what I can offer.
The Max. Pretty weak in power and I've seen axles broken off and chains break pretty regularly.
The Polaris. Big, heavy and difficult to maneuver. In addition, I just don't like the belt drive. They do slip when wet, I don't care what the manufacturer says. One almost left me in the middle of a river once while riding through overflow.
If you are using them in a farm setting or for work them I can see it as an option but in the woods tracked vehicles and 4X4 ATV's are best.
My 3 cents...
Inflation ya know...
