Well, we there are many series about a main character who is just really good at what he does, though perhaps not intellectually. An example would be The Irregular at Magic High School, or perhaps Chrome-Shelled Regios, or basically any light novel adaptation because main characters often have monologues about how strategically superior they are in light novels. The problem is you start getting into things like Sword Art Online, and I don't think a character like Kirito is what you're looking for at all.
Edit: The World God Only Knows works too, if you're into that genre or are willing to try it.
If you're looking for the intellectual stimulation rather than the power gap, then perhaps you should try the variety of detective series such as Detective Conan, Psychic Detective Yakumo, or Un-go.
