Are you happy, as an atheist? Does it content you to so be?

I am extremely glad to have been raised atheist. Our minds and our ability to reason and think for ourselves is an incredible gift, and a lot of religion seems to be about stifling critical inquiry and just accepting "truth" without question. That to me is a waste of a great gift.

As for the heaven/hell thing... if I believed it, I would agree it makes a strong case for choosing to be religious. Unfortunately it all sounds like a big con to me.
