True, '22 Leatherface was pretty tough, but he's not gonna beat Zombie Myers. He's done stuff like stabbed a guy in the chest against a wall and he pinned him to the wall with the knife. Also he was high enough off the floor that his feet were dangling. He's casually punched reinforced/bulletproof glass and thrown a grown man through it as well.

This one feat pretty much puts him above Leatherface in terms of strength.
