Well let's see....
Best: (not in order)
UNDER THE DOME
Honorable mention: INSOMNIA
Worst: (I don't hate any Stephen King book these are just my least favorites)
Mist (again I don't hate this, just not my favorite)
The least favorite of mine is Roadwork. The beggining was much to slow for me and I'm used to slowness, frankly it was bland. It got better at the end, the last 80 pages are so were pretty good.
My favorite is a tie between Duma Key and IT they were just both so good!
scariest is by far Pet Sematary, especially the last 50 pages, scariest thing I've ever read!
Under The Dome gets a bad rap, it seems that people either love it or hate it. I loved it! the 1000+ pages seemed to zoom by very fast, even faster than IT. I really loved it. probably my 3rd favorite
Misery I finished this book in about three days, I loved it and it's the first book I really loved.
Mist Was good it just wasn't my favorite. The ending in the movie was much better.
Insomnia I liked because it was so strange! and since I'm so strange it fit well with me!
THERE YA GO!
