imo, it would make sense for itachi and izuna to be better at using their pre-owned eyes better, since the eyes are theirs after all. but, one thing I must say, is that both madara and sasuke have more chakra quantity, and chakra compatibility than itachi and izuna. this would give them an edge, but ability-wise, itachi and izuna would better at using them. now, I heard something bout nagato not having the uchiha chakra to control it well (the rinne), but he did have it. what do u people think a sharingan is? he had uchiha chakra to make him kinda compatible, since the eyes he got were madara's. @namikaze, I have theory that sasuke got his base rinne by kabuto's side of the chakra/dna donation, and got the other (different/extraordinary) parts (aka tomoe and change-in-place teleportation) by having hago's chakra 'injected' into him.
