May be a mean sounding question, but I’m genuinely wondering why people would choose Arch/Endevour/whatever (NOT on steam hardware) over another all-in-one distro related to Fedora or Ubuntu. Is it shown that there are significant performance benefits to installing daemons and utilities à la carte? Is there something else I’m missing? Is it because arch users are enthusiasts that enjoy trying to optimize their system?
SteamOS 3 is arch based but that doesnt mean its anything like arch. It builds from a snapshot of arch and ships that to users as an immutable. So it will be extremely out of date compared to arch.
