Itachi wins in actuality. Itachi has full info on Danzo. You want to argue Koto, Itachi also had koto in his posession for 10 years. Izanagi, Itachi already knows about that.
You want to undermine Sasuke and wank Danzo but dont realize Sasuke had no info on an overpowered ability like Izanagi and a new sharingan as he was just getting use to his new powers and fought a battle with those handicaps still taking Danzo at high diff. If you think Danzo is going to win by simply outlasting then you really need to read the manga to understand Itachi stats are so much superior to Sasuke outside of stamina that he wont even need to susanoo to win this battle.
