Simple: on an Airbus, if you fall asleep, the aircraft will land alone, on a Boeing, unless you tell him to land during your sleep, it won't.
It's a question of automation and philosophy: Airbus aircraft are built around the computer. Boeing aircraft have a computer attached to the machine. Both philosophies have proven to be good, and both have their limits.
None of both is better, it's up to each pilot.
One pilot likes brunettes, another prefers blondies.
The question is which is the blond one? Airbus or Boeing?
