What type of update are you seeking? Price, quality, performance, satisfaction?
I know there are a few others who have made the plunge so to speak, but I am still very happy the Sulastics are on our truck. The price was worth it for the results obtained.
I have not heard from anyone who has the springs, complain about them not doing what they were designed to do. I feel like it would have been a mistake to go the shocks route, since they only make the ride stiffer instead of softer, especially in normal everyday driving conditions.
If you are looking for a more cushioned ride to the rear end, I don't think you can make a better choice other than loading a few hundred pounds of sandbags or maybe a water bladder in the bed of your truck.
Good luck and let us know if you make the leap!
