Always good to see Itachi on screen, every scene with him involved is quality.

I don't think we can compare Itachi's peak with Madara's peak. Itachi lived his live hiding his identity and not wanting to kill people for the sheer hell of it like Madara did. Madara also seemed to be a lot older than Itachi when he fought Hashirama and Itachi died young, so he didn't even have time to train and gain the same level of fighting experience Madara did. Itachi also didn't rob his brother's eyes for an EMS which Madara did.

I guess what I'm trying to say is Itachi never seemed to reach his true peak whereas Madara did, so it is not a fair comparison.
