The Airbus vs Boeing approach to fly-by-wire is a bit of a religious issue, like type safety or memory management in our world. Many words have been written on both sides.
I think the UI issue in AF447 is much less clear cut. It's more a lack of any indicator that pilots are making opposite inputs, rather than a misleading or confusing display. Airbus did not anticipate that a pilot would stall a plane and fly it directly into the ocean. There was a whole chain of events (including some appalling human factors) that led to the tragedy there.
The avionics teams at both companies have put an incredible amount of thought into how these systems are designed, and how they fail. The differences are instructive, but we should refrain from being quick to judge which is more or less intuitive.
