I don't know that Cracker is stronger than Doflamingo, at least not physically - he's admitted that he can't even stand the pain of a needle prick, whereas Doflamingo just kept getting up during his fight with G4 Luffy after getting shanked with a radiation knife. Cracker's power, and thus bounty, comes mainly from his Devil Fruit, which Nami was rendering all but useless.
