Poly binds and/or squeaks.
Delrin transmits notable vibration. And eventually squeaks.
Rubber just works. I didn't experience a notable loss of precision going back to rubber, either. While it's conceivable something would show up on the lap timer, it's not worth it for me.
Or, to put it another way, there's a real good chance you're unhappy if you go with something other than rubber. There's a 0% chance you are unhappy with fresh rubber.

I'd just add that sport rubber bushes are available for a tad more precision w/o losing anything else
