I am a little late joining the topic here, but I own both a T2 and a RZR4. The T2 obviously has the most power and we have never had any problems with it. We travel to Moab twice a year and run in the rocks. We also own a place in Lake Havasu and both units run great there. I live in Wyoming and ride here in the summer, but since we just bought the rzr4 I haven't ridden it here. The Rzr seems to ride much better, but I think there are shock upgrades for the T2 that would probably put it on par. I love both units, but for the money, I think I would take the Joyner. Take it for what its worth, I am just a newbie .
