Unless things have changed recently, Nordic is still king of low power applications.
With that being said, I've worked with both the Nordic NRF SDK and the Espressif SDK and greatly preferred Espressif.
For doo-dads that I make for my home, esp32 and esp8266 are fantastic. The modules are inexpensive and the community is huge. I would not want to be in Nordic's shoes right now.
