Well just think about it. Konan being close to Madara figured out a weakness in Madara's tech so Sasuke can figure out too. And because he is stronger than Konan then he has a better chance than Konan. I am not saying that Sasuke is stronger but all I am saying is he might be able to figure out a way to stop Madara's seemingly invincible technique which was only challenged once by Minato.
The only reason she was able to do that was because she spent weeks planning, did countless simulations, had over a hundred billion papaer bombs, knew madaras' weakness, tryed to be a suicide bomber and after all that she still failed:|. madara walked straight into a trap of an s rank akatsuki member and still won. and konan is not going to have a trap with billions of paperbombs, try to commit suicide and know her opponents weakness from the start. it's completly impossible for that to happen unless she knew ahead of time(atleast 2 weeks):flaw:
She beat him. I don't think anyone will just go and fight Tobi without preparations. Even Sasuke is preparing his EMS to fight Naruto. Tobi just changed the reality and made his death an illusion. He killed her in the end but Izanagi is just cheap especially since he has like 100 Sharingans in his little hideout.
