General & Others Buggy vs Mihawk vs Crocodile

Buggy has all hype and no power backing him up. Its difficult to gauge because of that how high his bounty would be. It could range from slightly below Shanks to lower than Blackbeard from what we know. He could benefit from the fact that the larger WG has no clue what kind of person he is, and that coupled with him being an ex-Roger crew member might very well push him past Blackbeard.
I'm expecting all of them having bounty in range of 1 B to 1.5 B . And Buggy having highest bounty among them..This guild is Walmart version of rocks.
