I agree with Mina on this!..
Itachi wasn't deceived by Obito which is why Obito feared him an probably Vise Versa.. LordCrow is/was no fool an he knew the capacity of the original Uchiha Madara's power through study of his clan which is why he declared Madara unfit to be the pinnacle of Uchiha power..
His abilities are counters for Madara not Obito if we think about his sealing weapons an Susano'o which Obito doesn't have..

In a way he wasn't lying.. His eyes allowed his lil Bro to go beyond what the alive Madara was unable to do in his life time without becoming A old man for the same outcome as Madara, minus edo to JJ status..
