It really depends, as a teenager I was very passionate about King, I found his writing style excellent and I enjoyed the thorough psychological analysis of characters.
Lately I have really gotten into Carlos Ruiz Zafon's work but I only enjoy it because of his fantastic imagination and I guess I read it for the story itself. I don't necessarily enjoy his writing style, I thought it was maybe due to translation but I read his books in English and Polish and something seems to be missing.
