Partially agree. If you're only using your PC to play Steam games and absolutely nothing else, especially if you want it to auto boot into Steams big picture ui and behave like a dedicated gaming console something like Bazzite is ideal.
But if you're using your PC like a PC and also doing other stuff imo it's better to install a 'regular' distro like Fedora or Ubuntu. I haven't had any difficulty installing steam and playing games on either of those.
