You know as well or better than most others
There are too many variables to say one is a better value than the others - They are all very good quality controllers
For me - No Fans, Small Size - Integration with the other devices for example the Relay Driver & Remote panel & Inverter - Ethernet interface with wireless compatibility - Firmware field upgradable - Available 3rd party interfaces - etc........ helped make my decision
Look at the feature set and what is important to YOU
They NOT are all the same
Price is only one of the differentiating features
