I would love people to actually prove how Itachi is magically above Sasuke, when EMS by default is the better ocular ability. Sasuke has mastery over Amatersu, has sussano sword and arrow, his genjutsu prowess makes him immune to Itachi's Tsukiyomi, the only point where he is above Sasuke.
He has CS that can be encased with enton Kagatsuchi for further defence, Itachi's prowess with Amatersu and Sussano offensives are abysmal. Sasuke has arrows, enton arrows and Magatama, and sword, while Itachi only has one measly sword and unimpressive Magatama. Sasuke's chakra reserves are tiers above Itachi's, there is such a vast difference that it's not even funny, and this difference is made even greater because EMS puts no strain on the body while MS sucks out the stamina and Chakra extremely quickly, putting immense burden on the user's body.
My god...stop this show of fanboyism and just accept it that Itachi is far below Sasuke now, in fact he is no where near the league of the current uchihas.
He didn't fight Sakura, Naruto didn't fight him either, he just stood there, and Yamato clearly stated he was about to go all out on Sasuke right before Orochimaru appeared.
At the summit? Sasuke got smacked around at the summit, Obito had the upper hand during his fight.
Obito wasn't stalling for time, he was trying to finish them off. The only reason he failed is due to Kakashi's Kamui.
Sasuke wouldn't be weaker by that much if he could put up a fight against Obito..but he can't, not when he has his 6 paths and the Gedo.
Sasuke got smacked at the summit? Really? He defeated Raikage, Kazekage, and 6 jounins, that's getting smacked? He also defeated and current Hokage? Are you serious?
