Which is better esp32 vs esp8266?

The ESP32 is much more powerful than the ESP8266, contains more GPIOs with multiple functions, faster Wi-Fi, and also supports Bluetooth. Many people think that the ESP32 is more difficult to deal with than the ESP8266 because it is more complex.

Regarding this, which NodeMcu is best?

Best ESP8266 Boards Comparison

	ESP-01	ESP-12E NodeMCU
Links	Banggood Amazon.com Aliexpress	Banggood Amazon.com Aliexpress
GPIOs	4 (including TX and RX)	11
ADC Pins	1	1
Flash Memory	1MB (upgraded version)	4MB

Also Know, is esp32 reliable? As Evgenios Skitsanos says, it's very reliable. That's only the chip, however. Things that will make it very unreliable are firmware and anything connected to it. Despite the maker style of the Arduino platform, in the case of the ESP32 it sits on top of the ESP IDF, Espressif's official offering.

Also to know is, what is difference between NodeMcu and esp8266?

The 30 pin ESP32 can be reprogrammed and has both wifi and bluetooth. NodeMcu is software that comes installed in a ESP8266 nd uses the Lua programming language but the ESP8266 that comes with NodeMcu can be reprogrammed via the Arduino IDE.

Is esp8266 secure?

Some devices, like the ESP8266, can be made to perform secure connections, but only when they are directly programmed. This can be undesirable if plenty of GPIO and peripherals are required. For example, the ESP8266 only has one analogue read input.
