one of the nice things is just not having a fear of always trying to reconcile your beliefs with the reality before you. If I had a nickel for everytime here or in real life someone is talking about searching or trying to reconcile their faith and beliefs with something happening around them. Not having to interpret any mystical non-applicable texts and trying to link it to what you experience in life is such a wonderful award that I wish I could give it to some of the "searching theists" at times.
I remember two years back I had a really painful tooth ache. I was at the dentist office about to get a root canal and my mouth was in so much pain. I was thinking without out a God whom should I turn to ease my uneasyness. the answer of course was the dentists his nurse and my brother (also an atheist) who was with me. I didn't have an invisible being who may or may, depending on his will, to look out for me, instead I had a dentist, a nurse and my brother, all whom wanted, without a doubt, to help me in any way that they could. They weren't omnipotent but they were absolutely committed to helping me at that time and not needed of an acient text to intrepret nor a preconciveved will on the subject.
In general learning to turn to your friends, co-workers and neighbors over God is a huge reward of being an atheist.
