Getting airspeed back is a higher priority. The aircraft will do that by itself, and get close to balanced, if the pilot would stop doing whatever they were doing to artificially create the situation in the first place.
Stopping further yaw with rudder is correct in a fully developed spin but most aircraft can maintain roll control through a stall and will only be yawing if the pilot is giving it a bootfull of rudder and has put it out of balance deliberately.
