JE EE:
If flying pitch and power is sufficient to keep the plane flying I suspect AoA and power is even better.
Except AoA isn't very useful at cruise airspeeds. At cruise speeds, AoA varies much less per knot of airspeed than at approach speeds. Trying to fly AoA at cruise speeds is like trying to balance on top of a bowling ball. Not easy.
On the other hand, when trying to prevent, or recover from a stall, AoA is exactly what you need.
