If the current Shichibukai never sided with the marines how high do you think their bounties would be?

Yea i had a hard time trying to figure which of them should be higher too, but the reason I picked Kuma is because he is by far the strongest shichibukai I've seen. I mean his speed is one thing but his devil fruit power is something that's on a whole other level. Plus if he didn't join the marines then he wouldn't have been part of Vegapunk's experiment. But i think the only reason the marines chose him to do the experiment on is because they recognized how much of a threat he would be if not completely under their control. I have no doubt in my mind that Doflamingo would be a great threat and perhaps be on par with the Yonko when it comes to his influence. But when it comes to brute strength and force, Kuma wins. Hence he would more than likely be considered a greater threat to the marines, well in my opinion anyways.

I'm not so sure there's such a difference in strength between Doflamingo, who easily dispatched Smoker, and Kuma, who was having difficulties with Ivankov. From a theoretical standpoint, based on speed, area of effect and perhaps defense (Kuma requires his hands for that), there's a case to be made in his favor, but I don't know if that would hold up in a pitched battle, especially since, in the One Piece universe, strength is rarely so straightforward, but I do see your point. My main disagreement, then, is that increased strength doesn't equate to increased bounty. Time and again, we've seen that it is acts of destruction or interference that raises bounties most. We would have to assume Kuma's previous role as a Revolutionary was very active, more so than Doflamingo's current role as Joker, and that's a stretch considering all I listed as Doflamingo's impressive accomplishments. I do think there is a case to be made for several of the Shichibukai (Mihawk, Kuma and Doflamingo specifically) to be given top seat in terms of power alone, but I would have a hard time justifying anyone with more influence in events aimed at wreaking chaos and creating powerful foes for the Marines than Doflamingo has managed to do. In fact, the best argument I can come up with against what I'm saying is that, without the title, he never would have been able to get this far - the Marines would likely have long since shut him down with extreme prejudice.

Haha Buggy would never even make 100 mil cuz he'd get captured before they could decide how much to put on his head.
