Back in the 1980s - the decade wherein I really got serious about comics - my favorite titles were Grimjack and Jon Sable, Freelance, both published by First Comics. What I loved about Sable was that creator Mike Grell really strove to keep the series rooted in reality, with his only concession to the super-hero crowd being the character's "battlemask" - which wasn't really a mask at all, but a kind of warpaint deal.
The stories were Men's Adventure stuff, and there was a bit of gun porn to it (Grell's a firearms aficionado), but Grell also tried to infuse the series with some depth of characterization.
As to the art - well, I'm a Grell fan, and although his figures could sometimes look rather awkward or stiff, I still enjoyed his sense of design and unique style. Unfortunately, somewhere around the twentieth issue, the interior art started getting progressively sketchier and more rushed-looking. I wasn't very happy about it, but I think it speaks to the quality of his writing and the strength of the character that I stuck with the book through its entire 50+ issue run (and it's relaunch with different creators, for as long as that lasted.)
