Crocodile fight/clash with mihawk and many other big names during marineford

Moria would win, prime moria was able to fight equally with Kaido.

Crocodile will win because he had many fights against mihawk and many strong pirates more than moria

Crocodile fought against whitebeard a bunch of times and lived to tell the tale and the government never thought about removing his position as a warlord unlike moria
