What is the best comic book ever?

I like Superman comic book. Without Superman, the first big comic book superhero, we might not have Spider man, Batman and the others. Due to the success of Superman, other comics companies pushed making superheroes and to that, Superman is owed a huge debt. Decades later, Superman is still going strong, with a movies in the works, multiple titles to choose from, and a hit TV show. The Man of Steel is certainly on top in terms of historical importance, abilities, and current popularity.
