I own both a P2V+ and a P3P. I am finally selling my P2V+ now that I am feeling more confident in the new firmware and GoApp.
There is no doubt that the P3A and P3P have many more advances. The App, the overall systems appear more refined but I am not sure about a P3S versus a P2V+ V3. The P3S is going to be new, have a factory warranty and a longer support life.
That said - many find the P2V+ as good and less constrictive without the new GeoFencing. There are still limits and there may be similar limits in the latest P2V firmware and Vision App. I have older versions and much fewer "restrictions."
