They are all in the same category except for Marco, he is the second strongest without a doubt before whitebeard's death. I agree with DP that they are all mostly in the same strength, but Vista is most likely the strongest swordsman among them, but he is mostly likely as strong as Jozu, with ace in the same area as that two but everyone can agree that Marco is stronger then all the other commanders. Though being the 1st or 2nd does not mean anything, just that there skills are that state and the gorseai see Marco in a different category then the other whitebeard's... In fact if whitebeard died naturally and Blackbeard was not in the picture, then Marco would be the closest person to be a yonko.
