I've just updated my list of "philosophically interesting" SF -- about 400 total recommendations from 40 contributors, along with brief "pitches" for each work that point toward the work's philosophical interest. All of the contributors are either professional philosophers or professional SF writers with graduate training in philosophy.
The version sorted by author (or director, for movies) is organized so that the most frequently recommended authors appear first on the list. What SF authors are the biggest hits with the philosophy crowd? Now you know! (Or you will know, shortly after you click.)
There's also a version sorted by recommender. If you scan through to find works you love, then you can see which contributors recommended those works. Since you have overlapping tastes, you might want to especially check out their other recommendations.
