I think the balance ship has already sailed at this point:
- Kaido and Linlin never saw each other (let alone fought) for decades.
- King and Marco knew nothing of the other's abilities.
King wasn't actually fighting against them headon in combat. And well, King is the only one Kaido brought along when he sought to assault Marineford/to combat the Red Hair Pirates.
Yamato doesn't matter as she was imprisoned on Onigashima and never partook in expeditions.
But I don't want to debate against Sweet Commanders > King.
