I really enjoyed the majority of Michelinie's run. Sure he had a flop or two here and there (what writer doesn't after so many years on a title?) but I just enjoy the heck out of reading his stuff. It was fun and a blast to read. I'd gladly buy another of his Spidey or Venom stories if they should ask him to come back. And for those of you thinking "Gosh that 'Round Robin' story sucks!", it was actually written by Al Milgrom. I can't tell you how many people think Michelinie did that story and hold him and his run to that particular story.
His Venom and Carnage stories were the best, and I don't think either character flourished as well under any other writer; I also loved his Acts of Vengeance/Captain Universe Spidey, his Sinister Six story was great, I enjoyed his Dr.Doom/Black Fox two-parter, His Spider-Slayer story was fun, and I thought he had a real talent for using classic villains and revitalizing them, too (Chameleon, Rhino, Scorpion, etc). And the guy created some really memorable characters; some more so than others, but most of them are still being used today in some capacity: Venom, Carnage, Chance, Solo, Cardiac, the Tri-Sentinel, etc.
In fact, I feel Michelinie's run was one of the last good classic runs on Amazing Spider-Man.
And no, I read the rules about being able to have Ditko/Lee and Lee by himself. I just chose not to add Lee by himself.
And color me surprised when someone leaves off Gerry Conway or Marv Wolfman. I loved the hell out of Conway's run (Clone Saga, Death of Gwen Stacy, Punisher, etc), and from what I've read of Wolfman's run thus far (don't worry, I'll read 'em all sometime soon), it was fantastic (especially his Mysterio/Burglar story); plus, Wolfman gave us Black Cat. If that doesn't warrant him a top spot, I don't know what does.
