I had Linux Mint several years, it's a great Distro on Debian/Ubuntu. But, as a heavy gamer, I needed fresh and up-to-date sources for Mesa and the Kernel and so I switched to EndeavourOS, which is Arch-based and I can highly recommend it! It's rock solid and gaming is great.
Been gaming on EndeavourOS since about 2 years. Tried Bazzite and CachyOS lately but came back to EndeavourOS.
