Cracker I would imagine is just over Doflamingo in power. On the same level as Jozu and Jack. (All speculation). So considering Luffy is stronger than he was in Dressrosa, and that G4 did work on Doffy, I bet he could get the upper hand on Cracker if he truly goes all out. I'm just not sure he'll be able to put him down before the time limit is up.
