One thing that's pretty much certain is that the Craftsman will cut a hell of a lot faster. With it's notoriously fast belt speed, I can guarantee the Craftsman 2x42 (which I have) will have at least twice the SFPM, probably quite a bit more, depending on the speed of the Grizzly. This also means fast heat build up, and it can catch pretty bad on higher grits. With practice though, it's quite a capable machine.
