@Tupka217 I think he means the best period, which to answer his question a comic like that will never exist. Because while DC is good and there are stories to show how good it is, there are also fans of other franchises who will never agree with you. Me personally I'm a fan of Marvel, DC, and so on.

Marvel and DC have both brought out good stories and bad stories. It's not a contest.

I'm aware of that fact, but I think this guy was trying to find a comic to prove that if it was that "DC wins"

You can’t prove something so subjective. That was Tupka’s point with his initial rhetorical question.

The killing joke a good backstory for joker one of if not DC best comics

Alan moore's swamp thing

Another good one to be honest with you about this.but still the killing joke for me .

@Arise Etrigan I'm aware

Superman for all seasons is pretty good. Same with trials of Shazam and Flash: Rebirth.

Either 'flashpoint' (the Flash) or 'hush' (Batman). There's a reason that both those stories were instant classics. Probably 'a death in the family' (Batman) too. *When Joker killed the 2nd Robin.
