sasuke because of plot lol but i dont know myself hard to say but i do remember when tobi implanted itachi's eyes in sasuke. and sasuke said he felt himself getting stronger and the great toad sage said Naruto will fight a young man with great power in his eyes so he has gotten stronger Mr.Kishimoto just doesn't want to show us yet.
itachi mid diffulcity, itachi couldve slaughter sasuke before....all he has now is no risk of blindness and actually he lost more during that fight then he gained from EMS (lost oro DNA,curse mark seal etc.)
Sasuke Uchiha, last living Uchiha, would win high difficulty.
Sasuke will use Susanno and amaterasu, forcing itachi to use his susanno and amaterasu which will give him eventual blindness, then sasuke finishes it off from there.
Itachi would win. Sasuke has gotten far too cocky ever since he obtained MS, so I can't imagine how sloppy he'd fight after getting EMS. Itachi would just capitalize on his silly mistakes and catch him off guard.

Itachi mid diff. He could have destroyed Sasuke, even when he was almost blind and sick. Cmon people, seriously? Itachi is so much more experienced with his Sharingan and wouldn't make silly mistakes like he did in their 1st bout, which was staged lol.
