I really like Arch and Debian, they are by far my favorite distros out there. In my pc I do studies, programming and gaming, so I went with Debian as my daily driver because it’s more suitable for a workstation, BUT, if my only focus was gaming, I would definitly go with Arch, it performs better and feels more smooth on screen. Gonna show below the avarage difference when playing Rocket League through Heroic Games Launcher:

DEBIAN - Using Flatpak version: 180fps. ARCH (wine from pacman) - Using AURk version: 270fps.
