Development boards for my workbench - which one to choose!?

[tarifa 0]

hello dear Community

currently i am ordering a bunch of tings at me german retailer. 

among them the following development boards are: 

- NodeMcu Lua WIFI Internet Development Board based on ESP-12E CP2102
- Adafruit Assembled Feather HUZZAH w ESP8266 WiFi With Stacking Headers
- ESP8266 ESP-13 Web Sever WIFI Wireless Shield for Arduino UNO R3

question: do i need more - or should / would you replace one of the above mentioned boards by another!? 

my main interest is to develop remote controlled cars ....  sensu

love to hear from you 

regards 

here the list - which one should i take - i guess i take all of them...

Feather is the (new) development board from Adafruit, and like it's namesake it is thin, light, and lets you fly! Feather was created to be a new standard for portable microcontroller cores.

The Adafruit Feather HUZZAH ESP8266 - a try to take on an 'all-in-one' ESP8226 WiFi development board 

- with built in USB and battery charging. 
- Its an  ESP8266 WiFi module with all some extras:

Feather HUZZAH's heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. 
This microcontroller contains a Tensilica chip core as well as a full WiFi stack.
 You can program the microcontroller using the Arduino IDE for an easy-to-run Internet of Things core. 
There also exist a wired up a USB-Serial chip that an upload code at a blistering 921600 baud for fast development time. 
It also has auto-reset so no noodling with pins and reset button pressings.
And a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. 
it will run just fine straight from the micro USB connector. 

Here's some handy specs!

The shield is designed based on ESP8266, and pin-compatible with Arduino UNO/Mega2560 DevBorad.

WiFi module is industrial-grade chips ESP8266, which is ESP-13 with metal shield, has strong anti-interference ability;

This shield is pin-compatible with Arduino Uno, Mega2560 and other control board. A voltage converter chip is used to deal with 3.3V (Esp8266) and 5V (Arduino);
Dual DIP switches is used for serial ports so that this module shield can be used alone as an Arduino Uno expansion board, and also be used as ESP8266 expansion board;
Serial data is transported to WiFi device transparently, and vice versa. Arduino program does not need any configuration;
Web Server is developed to configure WiFi parameters and serial port parameters;
This shield can be used as an independent ESP8266 development board. for instance, downloading the official AT commands firmware, NodeMCU open source firmware can be used;

This shield also can be used as stand-alone expansion board for Arduino Uno

well - the question is to consider a 8266 - and  why not just go dual core and get an ESP32 instead? For those times when we say, "Scotty, I need more power!"
