SoloCam E40 vs eufyCam 2 Pro

Hello, We just got a new eufy system for Christmas. We wanted a 3 camera system to cover our yard so we got the 2 camera eufyCam 2 Pro with base station and a SoloCam E40 which I thought was an add on camera for the base station. After setup I learned the E40 was really a stand alone camera and did not need a base station. Also, the E40 has a polygon activity zone which seems much better then the rectangle zone on the 2 Pro for my odd shaped lot. I am trying to decide to a) keep what I have, b) return the 2 Pro/base station and replace with 2 E40 cameras, c) replace the E40 with 1 true add on camera to the base station. Other Pros/cons: The base station can control all connected cameras with 1 click vs a click for each E40; The 2 Pro (on paper) seem to have a longer batter life vs the E40; Each E40 is another wireless device on my already busy wireless network vs the base station can be a wired device; and finally, 2 E40’s are $100 less then the 2 Pro/base station setup. Are there other pros or cons? What do people recommend? Thanks in advance for any advice and guidance!
