“I am using Raspbbery Pi Zero W for the screen in my car running Kodi, which is streaming movies and music from my wifi server running at Radpberry Pi 3.”
“The ZERO W outperforms the ZERO with additional USB WiFI. It's as stable as the PI-3 and the response times are very good. (especially when compared with cheap chinese usb sticks)
Next to this it's more easy make, with the help of NOOBS, the initial image as no USB port extenders and WiFi sticks are required.”
