Read em.
I prefer post-apoc books that deal with the direct effects and after effects of holocausts more so than ones that are more "storytelling" with an apocalyptic background. So for example, Alas Babylon GUD, A Canticle for Liebowitz....not as good. the Hunger Games is the "result" of some apocalypse but it isn't the story of it so although it's interesting, it's not quite in line with what i dig the most.
