There are two mainstream comic book publishing houses, DC and Marvel, and choosing between them as a kid was a bit like choosing between The Beatles and the Stones. They had different styles and sensibilities (and philosophies) and after a little bit of experimentation you could find a fit with one or the other.
DC had Superman and Batman — big, bold and (dare I say it) one-dimensional characters with limited or opaque inner lives. When Stan Lee created Spider-Man, a teenage photographer with powers he neither asked for nor appreciated, he created a soap opera — a soap opera with aspirations to high art. As you might be able to tell, I was a Marvel kid.
