Spider-Man and Superman have a lot in common regarding what they represent in their respective universes. Sharing a sense of optimism, friendly nature, and overlapping formulas for many of their stories, it's easy to see why a Superman fan might gravitate towards Spider-Man and vise versa. As much as they do have in common, they aren't all that alike, and there are plenty of strong differences between the two that change the nature of their comics.
