Novels give you more space to develop complex characters and inner thoughts. Comics, on the other hand, focus on visual impact and often have to convey a lot in a single panel. Also, the story pacing can be quite different. Novels can take their time, but comics need to be more concise and dynamic to keep the reader engaged.
The main difference is in the visual presentation. Comics rely heavily on images to tell the story, while novels use words to paint the picture in the reader's mind.
