If you take, say the older jockeys from Shimano, they were all bushed. Upto 105 had a steel bush and no rubber seals. Ultegra got a ceramic upper bush and contact seals, Dura Ace added lower ceramic bushings.
Guess which spins better...... 105. The ceramic bushes were better long term against corrosion. Certainly take alot less maintenance than bearings. SRAM needing regular checks given where the bottom jockey is located in the fireing line of spray and mud.
