I encountered this same question while replacing my clutch recently. I was advised that unless you have dead nuts concentricity go with a bushing because if there is any eccentricity the result will be poor shift quality. I went with a bushing. Car shifts smoothly now. Having both a bearing and a bushing prior to the install, I wondered the same thing previously mentioned. That is the hardness of the bearing versus the pilot shaft, and the fact that there was clearance between the two and any slippage that might occurr what would be the resultant effect. My advice.....go with a bushing.
