There's nothing to admit. Itachi was more impressive during their fight with Kabuto, and that's all there is to it.
Well, tsunade was more impressive than A in the gokage vs madara fight, does that mean she solos/is stronger than the raikage? Im tired of fanboys that say itachi is stronger than EMS sasuke with nothing to back up. Tsukuyomi has a counter in every uchiha, Long-ranged fighting, or simply not looking into his eyes. Totsuka is featless bar for a limp and a man that gave 2 flying ducks about Being stabbed.
On topic, sasuke is #3 in uchihas, but hes roflstomped by obito, and subsequently, by the #1, madara. PS automatically puts him on Ems madara level due to his Enton tho, and why would the spiritual weapons make a diference? As i said, both are featless.
