The best "angle of attack" for a propeller depends on many factors, the main ones being: the speed of airflow over the blade; the distance along the blade from the centre of revolution; the physical dimensions of the blade; the density of the air which it is trying to pull, or to push, to produce the force called "thrust" which drives the blade, and the aircraft attached to it, through the air. That is why the blade does not have a simple flat surface, but one which has many angles of attack along the blade due to the complicated shape of the blade.
