There is no single 'atheist morality', nor is there any single 'biblical morality'; making the ethical query in the OP all very confused. As has already happened, bad moral actors (God and Hitler) are immediately invoked in an effort to demonize non-existent moral codes by association.
The ubiquitous references to Hitler in these types of discussions are distractions. Hitler's belief or non-belief in God is immaterial, because Hitler's actions are universally accepted as immoral regardless of someone's religious affiliation; notwithstanding the existence of Mel Gibson and Islamacists.
Charges that Christians are immoral because the OT God was a prick are very superficial. Most Christians don't interpret the Bible literally. I don't have data to support this, but I imagine this is at least partially due to the fact that some believers can't reconcile some Biblical tales with their sense of morality and the idea of a just, loving and merciful God. Claims that someone can't be moral without a universal law giver are equally preposterous. When it comes to ethical debate, I put moral nihilists and literal Biblical apologists on the same psychopathic tendencies watchlist.
I just wish people would quit ignoring that meaningful ethical debate has been raging for thousands of years and that it is far more sophisticated than god/no-god. Virtue ethics, deontology, and consequentialism don't necessarily require a god, but they also don't prohibit the idea of a god in order to be meaningful and practical systems of moral guidance.
