I already run Ubuntu on my NUC, and when I was looking around to install on my former gamebox (i.e. computer with a graphics card unlike NUC with onboard graphics only) I wanted something with good steam/nvidia integration. It came down to either Pop! OS or Endeavor... because while I develop software I also want to play games without futzing around too much.

Very happy with Endeavour: pacman or yay for nearly everything, no hassle graphics drivers updates (system always suggests a reboot after and I always do that).
