It's a bit of a false dichotomy, there's a broad spectrum in both.
A lot of the benefit of religion doesn't come from the beliefs itself, but the community around them. You could just have a community built around other things, or even a religion that doesn't mandate theism (UU's and Quakers come to mind, they have fairly large atheist populations. There's also less "serious" religions, like TST).
