I'm a RainBird guy and switched a few years back to all SAM PRS, Check valved and Pressure regulated head. Easy upsell most of the time, some clients dont see the advantage of pressure regulation but most do if you explain it or show them. I have had excellent results. You can really tell the difference when you retro an existing system that was not properly designed.
