Those may be my top 3 until I think about it a little more.
Others are in consideration too.
I loved the first 2/3 of Tommyknockers.
The Dead Zone and the Green Mile were great too.
Under the Dome
Dreamcatcher
Blackhouse
I recently recommended the Eyes of the Dragon to a coworker. I like that one a lot too.
Finders Keepers
Firestarter
The Long Walk
Rage
Hearts in Atlantis and Different Seasons are my favorite short story compilations.
It's easier to list the books that I didn't like so much.
From a Buick 8
Joyland
Hmm... Everyone mentions the Stand and the Dark Tower series right away.
The more I think about it, the more I think that either It or 11/22/63 is my favorite.
