The funny thing about both guys, is they can get reckless in the cage and somehow not pay for it as badly as other guys in the division. Khabib will throw some careless flying attack, flurry then shoot, while Tony will constantly turn his back in the middle of an exchange and lazily return to action with a smile on his face.
To answer the thread topic, I'd favor Khabib in this one, especially if he shows no respect for Tony's antics. However, I almost don't want to choose a winner/loser. This is as close as you can get to an in-division super fight, if such a thing existed. Their worlds were meant to collide.
