Their debuts revolutionized their respective eras, and they’ve been used and abused by countless creators. THIS IS NOT about whether All-Star Superman is better than Spider-Man: The Other. That’s not much of a contest.
THIS IS ABOUT EVERYTHING YOU KNOW ABOUT BOTH CHARACTERS, regardless of the universe or timeline or era or any alternative universe. There is no “neither” option, because that would be weaseling out. (You can use the Batman option as a neither, but remember: You’re killing Batman).
I’m only posting this poll because, after 3,467 years of continuity (even the non-continuity stuff is really in continuity) suddenly THEY ARE BOTH DYING in series that are running at the same time.
