Surprisingly, it's hard to find lists of the "best" runs for DC characters that don't take place after Crisis. It seems that beyond Kirby's Fourth World, Wolfman/Perez Titans, and Moore's Swamp Thing, there is little love for the DC universe before Crisis. Granted, Marvel vastly outperformed them in the 60's-mid 80's, but I know that there had to be a lot of good stuff from DC as well.
Now I know that a lot of this has to do with Marvel bias (I've been guilty of it) but what I'd like to know is what are the "essential" runs for DC's major characters during this period? I'm already familiar with the best of Batman and Aquaman as far as Pre-Crisis goes, but what about Superman, Wonder Woman, Green Lantern and the Flash? Also, what would be the best periods for Batman and GL BEFORE O'Neil and Adams?
