ITACHI wins for 5 reasons.

1. rinnegan lacks the ability to read/predict movements. 2. no genjutsu resistance 3. tsukuyomi is unbreakable by users who lack the same blood. 4. great explosion clone 5. amaterasu

amaterasu > solves the animal paths issue, genjutsu from eye or finger will leave nagato vulnerable, explosion clone or crow clones will distract/trick nagato, perception will allow him see nagato's moves coming before it happens.

Honestly nagato's only win condition is CT or do what killerman said and summon his own 6paths users whatever. but again, that's assuming nagato isn't already caught in the gen. rinnegan maybe OP, but nagato is just one man and both chiyo and itachi quoted that uchiha's fight their best 1on1. so really, i'd argue 6paths of pain would have a better chance of stopping itachi, even with the power nerf.

Susanoo isn't needed at all

and according to kakashi, it's not about whether you can break gen, if you're caught in tsukuyomi, it's over.
