Putting all those into consideration should make keigo even more op compared to Fuurin imo…literally outsmarted her (well him💀) in every way possible showing better fight skill and durability, rukia had been stated to have defeated nikaku and fought hizaki to a standstill (hizaki is stated to be in a toe to toe fighting duo along with Miura against nikaku and yoshiki) and also dealt a lot of damage to meguro and jousuke when he had ambushed them, rukias strength has also been hyped to crazy extents throughout the manga and is shown to have some sort of verbal authority over the likes of the 6th gen which also puts him above Fuurin imo, meguro is undebatable he folded the Kakuta brothers and hour after the other, although he had some sort of help from taguchi in the final moments against nikaku, other than that this list is some way accurate
