Very nice and informative comparison, thanks. I have to admit though that I’m not that shocked by the results especially about the ESP32 Generic DEV Board with integrated Antenna
Personally I now only use the ESP32-WROOM-32D boards when it comes to integrated antennas, as mentioned a while back
as the ESP32-WROOM-32D has the antenna sticking out over the actual PCB, improving the reception substrantially, at least in my tests.
