Well, let's determine that when they're done fighting. For now, King may or may not have better feats than Queen, but his opponent Zoro has feats that far exceed anything Sanji and Queen have done. I guess that gives him a definite edge over Queen unless Sanji or Queen shows comparable feats to Zoro. King is also confirmed to be the undisputed number to 2 of BP which at least makes his superiority to Queen crystal clear.
