I could be wrong on this, but I think a friend had a JVC DD turntable back in the 80s. Seem to remember his JVC, in direct comparison to my Garrard belt drive jobbie, had more wow and flutter. Certainly picked up a lot of rumble.
Not saying for one moment that all DDs have this trait, but that is my vague memory of his hi-fi during that period.
I did read that DD wasn't necessarily as good with regards to wow and flutter as was led to believe. And since then, belt drive TTs have been continually improved. I doubt you'd hear any speed deviation on a good quality deck nowadays.
My first turntable was a plastic JVC thing which was belt drive. My mate had the exact sam turntable but belt drive. I was convinced there was something about mine that sounded a bit better...
