I suspect that a problem with rack and pinion 'back in the day' was materials and manufacturing mean they would wear and the steering would get sloppy. Where recirculating ball naturally is low wear. Once they upped materials and manufacturing rack and pinion was simpler and cheaper. I think for non power assist recirculating ball is nicer because it doesn't transmit road forces back to the driver like rack and pinion does. (Could be wrong)
