God, yes. Dr Mid-Nite ran a close second. I like the characters as conceived, but they sure could have benefitted from better creators.
ALL-STAR COMICS did have its share of fine artists over the years. Simon and Kirby, Mort Meskin, Jack Burnley, Joe Kubert, Alex Toth, Lee Elias, Shelley Moldoff But the title also filled whole issues with mediocre art, especially in the slack middle period.
