My dad once said to me, "You give a lot of books three stars." I do.
My reread of CoS this time included the audiobook (read by Jim Dale) and the illustrated version.
The audiobook is great. I'm not sure how I feel about the illustrated version. The illustrations are beautiful, but sometimes they don't match up with my own vision of Diagon Alley or Hogwarts or even the characters. I think they're nice as a supplement to the original series, but I don't feel any need to own these copies (the books are so large that I found reading this copy awkward).
