The only thing that'd give sukuna an edge is world cutting slash for which he'd need mahoraga....that and the fact that he's conscious of his soul so maybe he can also apply direct damage to the soul(not proved but it's a long shot..thought I'd try it) unless sukuna oneshots Madara at the start of the fight with the world cutting slash he has close to no chance. This is considering that simply maintaining eye contact with Madara will be fatal for sukuna due to the sharingan. It'll surely be a long day for sukuna
