It deepends on who you talk to, I personally like Ski-Doo and ride a Formula III, I've beaten XLT's, when my sled ran crappy, they beat me. I have friends that swear by Polaris, and than there are those of us who know better

Ride 'em both and look 'em over, that's the only way to decide. Each machine is different, and they both have their pro's and con's. Good luck.
