Itachi was terminally ill and on the verge of blindness and death, he then pushes Sasuke without killing him and in the process goes blind and is literally about to die until he actually dies. I would say that is the worst we will ever see Itachi battle ability wise, because he was blind and near dead and Obito bluntly made it clear that if Itachi wanted Sasuke dead Sasuke would be dead, he then muses to himself that if not for his "secret" which is Kamui's workings that he would be dead too. Itachi doesn't need tons of chakra or a continent busting move to kill/defeat somebody, his intelligence, skill, and the way he thinks are all what made him deadly to his opponents. EMS Itachi would have less chakra than EMS Madara and EMS Sasuke most likely but I don't see an EMS Itachi losing to them. I think EMS Itachi > EMS Madara = EMS Izuna = EMS Shisui > EMS Sasuke.
