List the definitive runs for these characters
Thor
Iron Man
Captain America
Hulk
Spider-Man
Ghost Rider
Punisher
Thor-- Walt Simonson
Iron Man-- Layton/Micheline
Captain America-- Stern/Byrne (though this was the hardest one-- could have just as easily gone with Brubaker, Englehart, or Gruenwald)
Hulk-- Peter David
Spider-Man-- Ditko/Lee
Ghost Rider-- DeMatteis/Budiansky (almost went with "none")
Punisher-- Garth Ennis' MAX series
Thor: Lee/Kirby (126–177), Simonson (337 - 382)
Iron Man: the two Michelinie/Layton runs (116-157 and 215-250)
Captain America: Englehart/Buscema (153 - 186), Stern/Byrne (247 - 254), the first half of MArk Gruenwald's run (306 - 375)
Hulk: Peter David (331 - 467)
Spider-Man: Lee/Ditko/Romita Sr. (Amazing Fantasy 15, Spider-Man 1 - 100), Roger Stern/John Romita Jr. (224 - 252)
Can't really help with Ghost Rider or Punisher as I'm not really a fan of either character.
Thor-- Langridge/Samnee
Iron Man-- Knaufs/De La Torre
Captain America-- Brubaker/Epting
Hulk-- Parker/Hardman
Spider-Man-- Lee/Ditko and Romita
Ghost Rider-- Aaron/Huat and Boschi
