The simulators have no accurate model to duplicate the behavior of the airplane post stall. Sure, they will exhibit a some sort of behavior (and I have personally flown it in several A-330 simulators), but if it reflects the actual airplane is unknown.
There are however, efforts to design at least a generic stall response for inclusion in flight simulators. Recent US FAR changes (that go into effect in 5 years) will require training in recovery that depends on this and other simulator enhancements just now being hashed out.
AF447 was a wake-up call in many ways. Many parts of the industry have woken up, but the fix is not complete.
For now, practice by turning off the flight directors and autothrust and flying some good old basic attitude instrument flying.
The flight directors are doing 85% of the brain work if you're hand flying with them on. Don't be a flight director addict!
