Ok Obito's win cons are
Kamui: Kamui can bfr him which would be a win con. But how likely is this considering the Rain dao domain? It's not likely at all.
Izanagi: Izangi is the use of sacrificing his MS to allow him to keep coming back from deaths for a straight 10 minutes. is this gonna outlive the Dao domain? No since the domain last for 8 hours. This also would mean Obito loses a win con, Kamui and his amps from the ms.
Rinnegan: Obito has the rinnegan but what has he actually done with it? Obito hasn't used its numerous other applications as Kakashi theorizes that controlling the bijus and using the abilities would drain him of chakra, so while he has rinnegan abilities he has never used them, and its detrimental for him to do so.
Biju bombs: The individual biju bombs are 6-C, Ji Ning is higher into 6-C going to the point he's reaching High 6-C but regardless if we use high 6-C or not this still means Ji Ning is above the biju bombs and he also can absorb ki so he would likely absorb them if he was gonna be hit by energy.
Jinchuriki Abilities: The jins have abilities such as, acid, lava, water bubbles, light attacks, boil release. Can any of these scale to where Ji Ning scales? No. Roshi's lava form isn't enough to even burn trees he stands on nor is the heat he produces enough to melt away his surrounding and it slightly damaged Kcm Naruto though he was able to hold on to Roshi. water bubbles? barely damage kcm Naruto, acid? easily dodgeable by Ji Ning, boil release? Han's boil release couldn't kill kcm Naruto so its not killing Ji Ning.
Gedo Mazo: Is this even in character for him to summon? Yeah it is but merely to deal with weaker people, and its soul hax is never used besides when Nagato did it. Can it seal Ji Ning? Yes it could but is it stronger than Ji Ning? No.
Genjutsu: Obito's instances of using Genjutsu are small, I mean small. When has Obito used genjutsu offensively? He didn't against Minato even though he stared Minato in the face when they first fought. Obito's used it on Konan for intel never to kill her, He used on Yagura to control him, never to kill. Ji Ning also has the ability to split his mind so Obito would need to target both minds.
