To be fair Touko is different from the usual bitchy/cold competitive protagonist. She is super nice.
I think an interesting comparison, at least in terms of Touko's character, can be made with Notes From the Garden of Lilies, where you also have a super-class-prez who's hiding another side of herself, albeit for different reasons.
That, I think, is an example of a solidly good, perhaps even very good, series within the familiar high-school setting that still doesn't come close to the level of YagaKimi (the art is not nearly as sophisticated, for one thing, and it definitely could have used more chapters for development and denouement).
But still worth reading, IMO (especially if you're interested in a Touko-type with a touch of the friendly sadist).
