I can't make the comparison because I've only had the DS, but I can refer you to a valuable resource not too far from you. Dr. Rabkin, of Pacific Laparoscopy in San Francisco, is one of the best revision surgeons around, including for RNY to DS revisions. He has a support group that meets monthly in SF, and anyone is welcome. He does an educational presentation the first hour for new people (I don't know how much would apply directly to your situation) and the second hour is everyone together. I haven't been for years, but it was a friendly group who were willing to share their experiences. Hopefully there would be other revision patients there, but if nothing else, you would meet a bunch of people living with the DS.
Details of time/location should still be on the PacLap website.
