Both of these are quite similar with regard to the horror and cannibalism stuff. The difference between the two, however, is that Tokyo Ghoul has a plot.

Both have a futuristic "Twenty minutes into the future" style setting that is mainly focused around a interconnected cybernetic world that at first appears to be a video game; but is later shown to be something else that has far more dangerous consequences and potential for abuse in the real world. Both shows also focus on the protagonist's circle of friends as equally as it focuses on him.

Both are general parodies of the Shōjo and Romantic Comedy genres, and they both involve romantic plots that are played for laughs and never really go anywhere. They also share a diverse cast of characters. School Rumble focuses more on a sketch comedy format with love triangles whereas Nozaki-kun focuses more on a slice of life format with recreational activities that bring the characters closer together.
