Basil Wolverton's Spacehawk is pretty solid. Kinda scifi-esque. The art is fantastic, specially for golden age standards.
Wally Wood's T.H.U.N.D.E.R. Agents is silver age capekino.
Veitch's capecomics are a little dark and fried, but all around pretty solid imo. The One. Maximortal. Brat Pack.

Question is do we consider Image, Wildstorm or Darkhorse non-big two?
Because those three are essential big-two companies just not the biggest ones.
