Sasuke was using Cursed Seal and Itachi was still fighting fireball to fireball with him while he was near death, only once Sasuke put MORE Cursed Seal chakra(which IS Senjutsu) into the tech did Itachi resort to Amaterasu. Itachi's Sword of Totsuka is instantaneous as Oro didn't even see it coming and couldn't even react to it till after the fact. YM blocked and bounced back Sasuke's Sword and his kunai and explosive tags showing it can reverse not only elemental techs but physical, explosive and concussive attacks. I have the episodes and the digital colored manga and I am looking at said things right now.

@Namikaze Killer B, Danzo and Ei both mentioned Shisui and Itachi being the best Uchiha when it comes to Genjutsu. Danzo knew Hashirama, Tobirama and EMS Madara since he was 8 going forward, and when EMS Madara "died" so we can take his words for facts on that.
