This Sasuke has no sealing iirc

Itachi has better showings of feats.

Their fight with Kabuto gives a pretty accurate comparison I think

What EMS Sasuke?

Itachi would win: Inexhaustible chakra, regeneration, best susanoo (at that point Sasuke hadn't perfect susanoo yet).

Even he could beat Sasuke just using izanami.

Sasuke doesn’t have sealing abilities so he’s fucked fighting the Edo version. Only time I remember seeing him seal anybody was sealing Kaguya with Naruto.
