Idk if this thread is talking about intellectual genius, or just who would win in a fight.. everyone seems to be arguing something different
If this is about who is smarter, the answer is obviously Kakashi
If this is about who will win in a fight, Unfortunately Sakura takes this with mid difficulty easily.... If she wants she can just sit on top of katsuyu and tire Kakashi and his low chakra reserves out..
The thread asks who is greater genius, yet you talk about battle situation when it has nothing to do with being genius. Neji is the genius of kid generation, yet he is fodder to the likes of Naruto, Sasuke and so on. Learn to read please. U_U
Besides which Kakashi even as a kid was superior to Sakura in every relevant category besides strength. With his speed, sharing an precognition, his use of kawarimi or clones, not only she is never landing a hit, but she is done for the moment she is either caught off guard or when they enter CQC. One raikiri is enough to own her at that point since she has no durability or regeneration feats. More like she does not even have durability or great combat prowess at all. Remember its the same Sakura who went flying by a single kick from a kid like Omoi. On the other side kid kakashi defeated the leader of the rock elite ninjas in charge of protecting the bridge
Sure at that point he could not hold sharing an for long but he doesn't need to to beat someone on Sakura lvl. Maybe he doesn't even need to reveal his sharing an in the first place
