Conversely, I look at a lot of OSR stuff and I a) don't think the worlds are more interesting than books, and b) I don't think they're as interesting as those old D&D modules were at the time.
A lot of OSR modules have settings that feel self-consciously derivative while also being so optimised for play that they don't feel real and so are not evocative for me, but then I know that I do tend to run worlds rather than games and OSR stuff is very gamey.
