The S2 lacks Bluetooth though, doesn't it?

The second core is meant to handle the network stack, leaving the first core to focus on program logic. With ESP8266s, it can be hard to write complex applications while keeping heavy WiFi usage stable.

Although, I'll bet the 8266 firmwares and libraries have improved a lot since I was using them.

The ESP32-S2 is best thought of as a spiritual successor to the ESP8266. If you need Bluetooth, I’m pretty sure the ESP32 is still being produced.
