You could get a lot more precise with stepper motors paired with a micro stepping drive. Since a stepper does not necessarily need feedback the software doesn't have to close a loop but spit out position and velocity commands. Integrated stepper chips exist on breakout boards which keeps the design simple as it will handle the complex microstepping current control. The entire design would not increase much in complexity at all and gain a massive amount of precision.
