Well the fact that Sasuke's eye power is stronger is proved by many genius shinobis, and his own Transmigrant self.

The only thing Itachi was holding back was his Susanoo. the only thing that he got lowered was his speed or reaction ability due to his disease or blindness.

It's a stated fact, and there's no evidence about it being powered down.

@Thekillman. Yes most likely he planned for Itachi to be a good guy, but he obviously didn't decide on which reason, and by the time he figured I say it would be about vote1, there would be no other reason for Itachi to do such a crime unless he makes Shisui a secret villain character who made Itachi evil.

Considering he could have shown characters like Danzo earlier at part 1 itself but the fact that I don't get is why did Itachi order Sasuke to kill his best friend? if he only wanted him to be a hero? like @AsianReaper. said, he could have just threaten Sasuke that hell vome and kill his loved ones instead of giving a Sasuke a reason to come after him with killing his friend.

@Kakashi. Itachi surely holded back with his susanoo, and he is suffering from either his disease or blindness or together(But I also read that he takes drugs and medicine to keep alive so I think it's probably blindness).
