I want to know the answer to the following question:
With what other device are stepper motors most versatile?
All the background I'm provided with is that "Simple stepper motor drivers entirely energize or entirely de-energize the field windings, leading the rotor to "cog" to a limited number of positions; more sophisticated drivers can proportionally control the power to the field windings, allowing the rotors to position between the cog points and thereby rotate extremely smoothly.". Is that enough to answer the question?
Answer: no
