@skorokithakis from personal experience, i'd say - no. :-D but it is already quite work and usable. many libraries are still missing in the official repos (webserver, websocket, ticker, SPIFFS, ping,...) but some of them are available someplace else. for me it is less stable then esp8266 also (for example the STA sometimes refuses to connect to the AP, the SoftAP does not hand out IP addresses when configured with a different IP then the default, sometimes the main loop just stops executing and no WD kicks in,...). but it is constantly improving and the devs do a great job!
