Kakashi easily wins, an hypothetical Alive Madara with Dual Rinnegan + SM lacks the base stats to even compete with any God Tier (Kaguya, Kakashi, Naruto, Sasuke, Gai, Obito etc). Juubi Madara is much more powerful than SM + Rinnegan Madara, and still Juubi Madara is trash to Kaguya, who had her techniques easily countered by Kakashi, who could also easily defend from her and counterattack and wound her.
Madara dies by Kamui Raikiri blitz, Kamui Shuriken spam, long range Kamui GG and so on. Linbo isn't doing shit here, Juubi Madara's Linbo (much faster than SM Madara's Linbo, since a Juubi powered body is much faster than a SM powered body, and Linbo is a clone with the same physical stats of the user) it is much slower than Rinnegan Sasuke, who was too slow to do anything against Kaguya's S/T, which Kakashi completely outspeeded with his long range Kamui. So Kamui GG happens far faster than Linbo. Not to mention that Kakashi camping in Perfect Susanoo or with intangibility makes that useless in first places, and by spamming Rikudo Perfect Susanoo slashes all around he can trash the Linbo clones anyway. Not that it does even matters, as Kamui GG is faster, by feats.
