Brought this to the Spider-Man section having read the one in Batman by LastSonOfShaolin.
Mine:
1. Stan Lee. Only choice for my #1. Classic Spider-Man, nothing better.
2. Brian Michael Bendis solely for Ultimate Spider-Man. Couldn't warm to his 616 Spidey.
3. Joseph Michael Straczynski. Surprised I've included him as he wrote the two worst Spider-Man stories ever in One More Days and Sins Past but I can't look past Coming Home, The Conversation and Doomed Affairs.
You?
