PROS
Small. Low wattage. Very powerful for size. Easy to program with the libraries available online.
CONS
Pin spacing is not standard breadboard spacing. The required 3.3v requires additional circuitry.
This easy to integrate into a Home Assistant smart home system. On one module I connected:
1. A DHT11 temperature humidity sensor.
2. Speaker to play rtttl 8-bit tunes (as an alert for doorbell, mail etc).
3. A bright LED (to alert people when the environment is too noisy to hear the tune).

I programmed the module with esphome. The first time with a FTDI module and cables. After that, updates are done over wifi. I still have pins free to add other sensors etc.
