A lot of people like to claim that Mihawk carries cross Guild, as he is the strongest member. And while he is the strongest, imo Cross Guild is only as dangerous as it is because of the 3 principle members: Mihawk, Crocodile, Buggy.
It’s like the chapter hinted;
Crocodile = Wealth
Buggy = Fame
Mihawk = Power
Mihawk might be powerful, but he has no charisma, nor even any ambition( as he already achieved his goal to be WSSM). Mihawk by himself could never amass the army that Buggy did via his luck and charisma. And as we know, having a powerful crew is an integral part of being yonko.
But even with Buggy’s crew, he still needed funds from Crocodile in order to get his business started. Crocodile is a schemer, he is the brains of the organization, with Cross Guild being his idea.
Ultimately, due to his influence, Buggy is an integral and valuable part of Cross Guild. Cross Guild is an organization that is greater than the sum of its parts.
it's truly over for me
