I use yaw to great advantage all the time, so much so that I can't imagine a stick without yaw. With 3 rotation axis on one hand and 3 translation movements on the other hand, I can't imagine switching to peddles as I use yaw so much. The yaw on the ships are not equal, some faster yaw than others. If you don't use yaw much, then IMO you aren't taking full advantage of the flight mechanics during combat, takeoff, and landing procedures.
