Even a sham like Big Meme established an entire nation and global mafia enterprise with countless islands under her rule. Meanwhile Crydo only had an out of date shit hole full of useless ronin and shinobi, a giant skull and a crappy factory island under his command while Doflamingo did most of the actual legwork for his fucking enterprise and SMILE production to the point where he was an actual Underworld Emperor.
Crydo is a bigger fraud than Big Meme on a global and corporate scale.
