^ Figuring out Danzo's strategy? Completely incorrect. I do not need to reread the manga, as I am completely certain of this. You should skim through the same chapters and see for yourself. She actually tried to throw Sasuke off his track at first and only figured out later, when Sasuke was already going at him hard and fast to compel him to use all his eyes for Izanagi.
And this should negate KA, going by its logic that the user completes the command directed by KA? We both know it was a poor use of KA, considering how it broke Itachi out of his Edo hold. Not it's not. Madara's Mokuton is like piles of wood on top of one and another, Hashirama's is far more dynamic. Not to mention the additional Mokuton techniques we saw during the flash back, Madara has none of them at his disposal.
To control the Gedo Mazo and as mentioned by requirements, Obito's control is better. Obito's Rinnegan usage would also be better by default. Hack, Madara completely absorbed Rasanshuriken with Petra Path in the blink of an eye, whilst Nagato hasn't displayed anything along these lines. It takes him a while to completely absorb chakra.
Obito's Kamui is both offensive and defensive and is tiers above Kakashi's.
