My experience is slightly different from Richard's, probably becasue we have different concerns.IMO there are four areas where brushed DC motors are lacking at the current state of play.
They are designed to run at far higher speeds than are typical in TTs and with far lower radial (side) loads), so the bearings wear out quickly. As long as you accept that your motor will need replacement about as frequently as your stylus, this is possibly OK.
The other three are technical flaws with the control circuits due to commutation noise, thermal drift and long term stability. All fixable with the right circuit. I'll elaborate if asked but the explanation is very long and technical.
