Are more turntable motors better?

I did a quick search of the archives and couldn't find a thread about this, feel free to show me if I didn't look hard enough. Question is: are more motors better in a belt-driven table? Seems like pricier models are always more likely to have more motors, and manufacturers offer addtional motors as upgrades, but does it always result in improved sound? Theoretically, additional motors may tend to cancel out each others speed fluctuations, but overall noise may be higher. Thoughts?
