There both martial arts manga that involve secret underground tournaments. In tough Kiichi is becoming stronger so he can defeat his evil uncle who believes only the strong deserve to live, Baki on the other hand is becoming stronger so that he can defeat his evil father who believes only the strong should survive. Besides lots of similarities in the story the artwork is also very similar and if you liked one I would recommend the other.
