Kisame is waaay faster than V2 Bee underwater, V2 Bee is faster and stronger than A in his V2 cloak, correct? So do what you will with that info, but I think that that puts Fused Kisame (while underwater) comfortably ahead of KCM1 Naruto in terms of speed (while underwater).

Also, I'd say Edo itachi is firmly above EMS Sasuke in that fight.

That statement contradicts feats and implications in the Kabuto fight. I don't agree with it.

Not really, Itachi just had a better idea of what was going on, what he had to do, and Kabuto's abilities

KCM1 naruto is confirmed light speed and you can’t compare swim speed to land speed, there’s different factors

Proving my point^

Itachi didn't know shit about Sage Kabuto @EmilioRory10

He still knew more than Sasuke, and he also stopped Sasuke from killing/trying to kill Kabuto, Sasuke was mostly confused and he didn't know much about his own abilities, he didn't know Izanami was a thing/wasn't willing to use it, the fight doesn't prove Itachi to be Sasuke's superior at all other than IQ which is obvious

I can agree with that, I suppose Sasuke doesn't have any anti-feats other getting his life saved bc he's dumb.
