I have actually done a fair amount of informal testing on this subject.

IF you use a GOOD bearing...one that has a teflon, kevlar, or other composite liner in it, that doesn't get loose over time...I think the noise is less and the ride quality is better. I know that durability is better.

If you settle for a cheap bearing then noise and ride quality suffer.

We have switched everything over to a nice american made kevlar line bearing with great results.
