The EP8266 is great: It gives your IoT device WLAN and IP connectivity for only a few bucks.
Bugs are not limited to software - plain electricity can be tricky, too! Sometimes it even kills (and I'm referring to Arduinos here).
 
On the other hand, the ESP8266 is quite a hand full: It creates power spikes that have negative impact on its own operation and possibly that of your circuit, it experiences out-of-the-blue resets that have to be dealt with, and it suffers hang-ups that can only be cured with a hardware reset or uttering "The IT Crowd" mantra ("have you tried turning it off and on again"; https://www.youtube.com/watch?v=nn2FB1P_Mn8).
 
I have had A LOT of problems with the ESP8266 before I had a lot of fun. Some can be solved with the proper power supply, a bit of hardware, and somewhat sophisticated error handling. Other, more persistent problems can only be addressed with resetting the chip or even cycling the power.
