It really depends on personal preference. DC often has darker and more brooding storylines, with iconic characters like Batman. Marvel, on the other hand, is known for its more relatable and humorous heroes like Spider - Man. In the graphic novels, DC might appeal to those who like complex, multi - layered stories, while Marvel could be great for fans of action - packed, fun - filled adventures.
In general, DC tends to have darker stories. Their heroes face morally ambiguous situations and the villains are often deeply disturbed. For example, Batman's Gotham City is a dark and crime-ridden place.
