I can't answer the poll as I really don't have a preference. When I replaced all the tires, the installer used balance beads, with my approval. About a year later, I had Borg dually valve stems installed on the rear tires and the shop removed the balance beads and spin balanced the tires. Since then, the rear tires that were spin balanced and the front tires with balance beads seem to be working well.
Seems to me that spin balancing is tried and true, but changes to the tire due to usage will require rebalancing at some point. The basic science of how balance beads would seem to indicate that balancing may last longer, but you don't know how well the beads are holding up or disintegrating into powder and could cause problems with the valve stems.
