DC's mainstream stuff was mostly quite bad, but with some great bright spots;
Robinson's The Golden Age
Waid's Kingdom Come
Good list. I'd add Peyer's Hourman, but otherwise that's the creme of the 90s.
I do differentiate DC's output from the early 90s, which was mostly crass garbage. DC was all about carpetbagging the shock storytelling of the era to create whatever sales it could - death of Superman, Knightfall, Emerald Twilight, Zero Hero, etc. Basically - "Let's crap on ourselves and see if people notice!"
But late 90s DC? Some really great stuff, especially wherever writers like Morrison or Waid were involved.
