Cool Contest! Gotta go with the RZR-4. I have hundreds of miles logged in the 4 and it is by far the smoothest riding UTV and as big as it is it's still one of the fastest. Polaris responded to the needs and wants of the UTV market and brought the 4 to the table incredibley fast.
The Can Am was a huge dissapointment for me. When i saw it and sat in it I thought Hmm? Pretty nice machine. but then I drove it and it and I could not beleive that they missed the mark that badly. Just my 2cents.
The rzr4 is cadillac in the dunes.
