Could go either way.
I would say Tobi though. Madara is great n all but 6 Biju is too much. He'd use Shinra Tensei to get rid of a TBB and then get another 5 in the face shortly after. Until we see exactly what TBB does to Susanoo though, we won't ever really know.
The meteors could be an issue but again, a TBB might get rid of em. While Madara is trying to use meteors, a TBB could hit him in the face.
It's kinda just too many versus too little. Naruto managed because he had the speed to cover the whole arena.
