This is what Madara says about Complete Body — Susanoo: "It is said that once anyone sees it, they die."

That is like saying, "It is said that if you break mirror, it will bring you seven years of bad luck", or, "It is said that anyone who drinks spring water of Mount Fuji during fullmoon becomes immortal".

Not quite sufficient proof, as someone would like to believe.

As for boasting power of Susanoo, Madara's armoured Susanoo(the one before CB — Susanoo) was not only as big as complete Kurama, it also blocked Kurama's Tailed Beast Ball, which Hashirama captured with Wood Human and used it as sort-of-Rasengan against Kurama.

So yeah... Not quite convinced.
