I can’t really say why I think DC is “better” than Marvel. In my early collecting days before I stopped for financial reasons (1987-1991), I purchased far more Marvel titles than DC titles. Part of that was the fact that my then-favorite Marvel characters — The Punisher and Spider-Man — had something like seven monthly titles between them, and I bought them all. Also, at only $1.00 an issue, it was easier to get sucked into continuing to collect various titles after I’d purchased them as part of one of the near-constant crossover events, which meant I ended up buying every X-title every month.
At the same time, DC came out with a lot of new titles I really enjoyed, but for whatever reason the ones I liked kept getting cancelled after relatively short runs. (Of course this still happens - witness Manhunter, a great title that was cancelled after just 25 issues, then was saved by a letter-writing campaign … for two more issues.) The result was I had fewer long-running DC titles on my pull list than Marvel titles. By the time I stopped collecting in 1991, my collection contained probably 500 more Marvel issues than DC issues.
Even back then, despite collecting so many more Marvel titles, I liked DC characters better in general. My biggest argument in that direction was that it seemed to me that every DC superhero had a unique origin story - every character got his or her powers in a different manner. Marvel characters, OTOH, all seemed to have acquired their powers through accidental exposure to some form of radiation (for the non-mutants) or were born with them (the mutants). In both cases, of course, I’m ignoring characters who are deities or aliens.
I resumed collecting in 2004, and since then the gap between Marvel and DC in my collection has shrunk to maybe 300 issues as my DC issue count slowly catches up. My current pull list is the shortest it’s ever been, but it’s heavily weighted in favor of DC at the moment:
DC:
Batman and the Outsiders (replaces old Outsiders title)
Blue Beetle (one of the best titles out there at the moment)
Green Lantern (my all-time favorite character, and very well-written right now)
Green Lantern Corps
Justice League of America
Supergirl (I may drop this if the art doesn’t improve dramatically, and soon)
Legion of Superheroes
Marvel:
New Avengers (which I’m close to dropping thanks to the almost painful-to-look-at art)
Runaways (excellent title, but very behind schedule lately)
X-Factor (great writing, though I’m a bit annoyed with the current crossover story, because I’m refusing to get sucked into buying the other related titles this time)
The thing is that lately, I’ve just had a really hard time finding Marvel characters that I care about enough to buy. When I do, there’s often some other factor that turns me off, like crappy (IMO) art. I’ll compare this to Buscema’s run on Daredevil in the late '80s - early '90s. I heard so many rave reviews of the writing on DD at that time, but I found Buscema’s art so unappealing that I just couldn’t bring myself to buy it.
I feel that Marvel is trying too hard to make it’s characters more “human” by giving them personal problems. That’s all good … at least it used to be when those personal problems were merely a part of the characters. But it’s gotten to the point where the characters’ personal problems have become the focus of too many stories - see the recent events in Spider-Man’s life. When I read superhero comics, it’s because I want superheroics. Even in Marvel’s “earth-shattering” events, the main thrust of the stories is that Villain X is causing trouble for Hero Y and must be stopped - all of the actual “earth-shattering” is merely collateral damage. What’s happened to Villain X trying to destroy/take over the world and Hero Y stops him? It reminds me of why I never really enjoyed Saturday Morning/After School cartoons - GI Joe, Transformers, Superfriends, etc.: every episode featured the group of heroes fighting the exact same group of villains, and those villains apparently existed only to attack this specific group of heroes. The whole thing lends much credence to the idea that supervillains exist only as a result of the superheroes.
