In the opinion of an atheist such as me, none: Derrick is right. I can't actually believe in some supernatural god to find answers because I prefer drowning among questions.
However, if you feel you have faith, if you believe in some eternal mind to watch over everything, I think you should consider that all religions are different ways to that God (even different gods might be just different aspects of an only one) and there isn't a best one; so you just choose the one that best deals with your own culture/living. But be REALLY faithful and religeous, not in the bad ways mentioned by Derrrick, which unfortunately are very common!
