I know here on /co/ we give him a lot of shit for his possesive nature on the web-head, OP here included; but lets look at the good things he did for Spider-Man:

>New Ways To Die: Dark Reign was the last good event at Marvel, plus JRJR's stuff
>Anti-Venom; redeeming Brock in a good light advancing his character
>Big Time; which gave Peter Parker a stable job fitting for him as a scientist
>those few tie in issues with Future Foundation
>Spider-Island: Which marked the return of Kaine and his tenure as our favorite Scarlet Spider
>Superior Spider-Man, one of the best Spider-Man stories in years and a fun take on him (even if other writers did SpOck MUCH better)
>Spider-Verse; writing was terrible but it was such good fun and it brought back Spider-Man Noir
>Not once did Slott ever make Peter Parker "poor" and force him to cliche as a photographer for the Daily Bugle.
>Brought back Ben Reilly (not in the best state, but Peter David is polishing it up)
>Keeps Peter away from Bendis' hands

now we can also argue that he was bad:
>Writing has never been god-tier but it hasnt been bad enough to make me drop it, just the right amount of mediocre
>nearly a decade run on ASM, way too fucking long
>Refuses to keep Peter Parker in a stable relationship with ANYONE
>Has had so many chances for a perfect end to his run, but the man will just not leave
