Sasuke shits with super low diff.
-Physically superior. Sasuke matches Adult Naruto at full power, who is >> Kid Naruto=Madara's Limbo=Madara in physical ability.
-Speed. Sasuke matches Adult Naruto, who is > Kid Naruto who is > JJ Madara. Same goes for reaction speed and all that jazz.
Madara's only way to defeat Sasuke, or anyone of this general level, in this form would be Bijuu Dama tree, which Sasuke either tears apart, or uses Ameno to dodge by entering another dimension. Make it two eyed Madara and Sasuke would still eat him alive.
