The Grizzly has a lower seat height, and is narrower for better trail and woods manuverability. The Cat was slower in the Dirt Rider shootout. If you look at the machines, it is clear which is built better, and has better mud protection for the rider-the Grizzly. Plus M10, you mention a winch, that is not standard on the Cat, so why list it.
