I haven't read Slott's Spider-Man but I was always really fond of his The Thing, She Hulk, and Silver Surfer runs. He has a really intuitive understanding of tone and (perhaps a niche concern here) works with continuity [i]very[/i] well. His Avengers: Initiative with Gage was really good too.

Oh, and [i]this[/i] Mighty Avengers run was perfect.
