I am assuming that when you refer to the XF250, you mean an XF250 controller? It is up to you. They both accomplish the same thing going from different angle. The Advanced controller can do a lot of what the APEX controller can do automatically without programming. If you do not like programming, then the Advanced Controller is the way to go. If you do not mind programming, then you have more versatility with the module as you can have the pump do exactly what you want without limits. So there isn't a straight answer to your question. It all depends on your preference.
