I would go with the Lolin D1 mini, it's better designed and has a more convenient form factor, in my opinion.

Having worked with a ton of ESP8266 variants, I agree with this. (The D1 Mini Pro has more RAM and is great.)

The ESP32 is good out of the box, and can be even better if you need dual core or Bluetooth.
