Madara is weaker than itachi or sasuke if you discount ms.
That's really what madara was known for. I've never seen or heard anything about his basic skills as a ninja but people (fanboys) tend to create mental illusions that madara was some sort of all around expert genius at everything from ninjutsu to taijutsu to genjutsu etc.
But we've seen next to nothing. Although he probably is superior to most people in those regards, he's not anything significant. Well he does have fire style...
Edo madara using 3 tomoe wrecked 100+ SA shinobi at the same time using taijutsu and weapons going untouched.
Completely blind madara blitz and shit stomped sai and sm naruto with a simple kick and hurt naruto with a ash jutsu. The fact that he can blitz an sm naruto is one of the greatest feats of speed nobody other than other senjutsu users blitz senjutsu 8th gate gai and blind madara are the only non senjutsu users to do so.
In his battle with hashirama he used his fire jutsus to counter hashiramam wood forests.
Intelligence is probably the highest.
He has knowledge of almost every jutsu and he can perform other people's jutsu and abilities with ease... Like juubito couldn't use kamui but Godara did instantly on his first try ever. Or like him absorbing hashirama senjutsu and mastering it in seconds and laughing at the amount of it.
Madara was the truth hands down quit hating
