I am an all out Polaris guy, but I have ridden both the xp chassis and the new M chassis, and i would def go with the Cat! they handle so well! normally it takes some getting used to a new sled, the M chassis takes about 5 minutes and your a pro on it. I have probably put in about 5 hours total on a skidoo XP, and still havent figured it out, just dont like them... either Cat or RMK!
