AOA works instantly, regardless of weight or load factor. Flying off one gauge, the pilot can max-perforn any type of aircraft. This is a lot easier than trying to fly "in and out" of stick-shaker. Most pilots who have flown both systems, instead of prefering one over the other see the benefit of having both. AOA to fly out of a bad situation and stick-shaker as a back-up. AOA also serves as great insurance against posting the wrong approach or climbout speed. Stick shakers simply tell you you're going to die if you don't accelerate -- but not how much to accelerate. Speed-up too much and you might not clear the trees in a windshear escape scenario. Normally I'm not one for government mandates, but I think it's appropriate in this case. If the AA crew in Cali had an AOA gage and a speed brake - thrust lever miscompare warning system they would have lived. That's pretty clear evidence.
