Want your thoughts guys. This is IF they both have knowledge on eachother. Kakashi has Kamui, and we've seen the speed that it warps people. Itachi doesn't have the speed to dodge it. Kakashi is also able to spam it quite a few times. Itachi has Tsukuyomi but that won't work if they both have knowledge on eachother. Amaterasu is his only other oneshot in this match, since Kakashi is fast enough to dodge Totsuka. Amaterasu didn't kill the Samurai and Karin wasn't badly hurt by it. It will not end Kakashi immediately but Kamui will end Itachi straight away. Kakashi also has more stamina than Itachi; Itachi got a 2.5 in the databooks whereas Kakashi got a 3, and we all know Kakashi's stamina has gone up since then. I think Kakashi would win this.
Kamui GG is real. It's canon now. Accept it. Believe it.
