The Joker has never really broken the forth wall, but does view his apparent insanity as some kind of "super sanity" where he realizes that morals don't exist and are just fabricated lies and that life is a joke, hence his name. He believes that "one bad day" is all it takes for the sane to become insane. Deadpool, on the other hand, is a more relatable character by comparison, if only that he is a mercenary that follows a moral code, even if it is a loose moral code. He is a sociopath, which is the result of the experiments of the Weapon X program. Therefore, I think that the Joker is a more insane character.
