Hi:

I have 4 Deco X20.  Two are Deco X20 (2-pack) US Ver:4.0 and the other is Deco X20 (2-pack) US Ver:1.0.  Which one would be better to set as Main Deco? Deco APP shows different features and looks V1 better with more options such as Network Optimization and speed ISP test that V4 does not have.  This is is rare due to V4 being higher and the newer version should logically be better.
