With a "normal" dc motor you can only control revolution
and the torque. With a stepper motor you can "step" exactly a given angle. Further the stepper motor has the advantage of having a holding torque. The disadvantage of steper motor is the ability of missing steps. If you can desribe your task more in detail, I can help you choosing which to use.
