What's your favourite ESP32 board? (# Best, good, cheap, quality, reliable)

Just found an ESP-01 variant I have not seen before on Ali Ex. [T-01C3 ESP32-C3 #2] The T-01C3 uses the ESP32-C3 and has the same form factor and pinout as the original and could be a good replacement where bluetooth is needed. More info here: https://github.com/Xinyuan-LilyGO/T-01C3

Maybe these.
