I mainly prefer inventory and story-based puzzles in adventure games, but this is not a general rule. I also enjoy a well-put-up-together logic puzzle, especially if its well-integrated into particular title and its style. For instance, the puzzle you've mentioned: torn-up letter or document is a great nerve-twister in games that feature an interesting and tense story. I could mention at least a dozen adventure games which I like specifically because of their puzzles, but if I really had to choose, I would probably put "Sherlock Holmes" games among my favorites in that respect.
