The RP2040 doesn't have a good low power sleep mode. It uses several hundred uA in sleep and dormant mode versus the ESP8266 which uses only 20uA in deep sleep.
This makes a huge difference for sensor systems etc. A pico/RP2040 cannot be powered by a battery for very long.
I never tried to explore the Pico deep sleep indeed. I used it with esp32 with great results even if the wake time of 200 ms does not make certain applications viable. Thanks for the point.
