You wouldn't have to go to church. No doctrine. No reading or listening to sermons or silly requirements like confession, praying etc.
Ethics would be a matter of gut instinct. Do what you think is right and don't try to harm others.
You would never have to argue your beliefs because you've already acknowledged that these things are "unknown or unknowable". And thus you wouldn't have the close-mindedness of Christian or atheist.
On the other hand, you're open to both possibilities - the God exists and that he doesn't. The whole idea isn't really relevant to your worldview.
I like things that are easy and simple. I think I'm going to be an agnostic.

* I'd say the Bahá'í Faith would be pretty easy to follow as well. It stresses the "spiritual unity of all humankind" and builds its tenants from Abraham, Buddha, Jesus, Muhammad. A potporri of spiritual beliefs.
