As I understood it, a stateless session behaves as if the only object
known to it is the one you just inserted. Personally, I look at it like:

stateless -> propositional logic
stateful -> first-order logic

I'm not sure that's 100% true though. In any case, it depends on the
kind of questions you like to ask. If you're not sure, test it.
