He's clearly the best QB in the league. Even if you didn't show that statistics I'd still say the same.
The other QB's you listed can hit the level Mahomes plays at (sometimes), but the consistency is not there. Allen and Burrow are prone to far more mistakes than Mahomes.
Mahomes has more mobility than Burrow which is a major factor, and Mahomes does not make the same boneheaded decisions that Allen does.
Hurts has been excellent, but it's hard to rate him against those three right now. Not a problem if someone prefers Hurts right now, but we'll see what he does come January.
