4x4 atv vs 2wd sport atv-trail riding HD

Yamaha Grizzly 600 4x4 vs Yamaha Warrior 2wd sport. The Grizzly is more powerful, its faster, and it can go through more mud and snow, but can it beat a Warrior on the trail? You decide for yourself. The Warrior is obviously only 2wd and the Grizzly has 2wd/4wd option but I think it was in 4x4 most of the time. The Grizzly has 25" Swamp Witch tires and the Warrior has 22" Bearclaws on the rear.
