Which Madara? I'm assuming Madara after he came back to life.
Madara can absorb anything Obito and Nagato have to offer, While Nagato can only absorb so much of Madara's Arsenal.
CT gets countered by PS Slice, If Obito tries to teleport infront of Madara and try engage him in taijutsu he will lose badly.
Madara takes this low-mid diff.
