This^^Edo madara, rinnegan madara, and juubi jinchuuriki madara basically neg Itachi. But I'm not convinced that EMS Madara is beating Edo itachi or Alive Itachi with no illness. I personally don't see it.
Im going with this but, madara will win if he cant match his perfect susanoo.. (ms vs ms) im assumingItachi > ems madara (without intel)
That's just it. Without intel i can't imagine madara (someone who usually toys with his foes and half ass in battle) actually go hard on itachi w/ precautions and perfect susanoo before getting solo'ed by totsuka or tsukuyomi. Think of all the times ems edo madara (or alive one for that matter) let himself get hit on purpose or was flanked by someone even such as tsunade(gokages). Imagine had it been itachi (someone who doesn't drag on fights against potential threats ie: orochi and nagato). It's GG imoIm going with this but, madara will win if he cant match his perfect susanoo.. (ms vs ms) im assuming
