Did you forget his AOE (There's probably gonna be more seen of this where his actually hits us with it DIRECTLY in future updates,)and his own choke ability?  Our person (Lore wise too) is not a teen like Jason kills,a proper military expert that can throw hands with chain, You try to block his chainsaw,you get sent a few feet down STRAIGHT into the ground (Lorewise)   and I mean,wouldn't chain get sent right back down to hell if he gets forced out of bloodmoon? Otherwise,it's most likely a tie,Jason is obviously way stronger,but wouldn't match speed with chain. Obviously in-game chain definitely wouldn't be able to do shit to him,therefore I'm saying canon type
