I'll chime in here; while I'm in one of those niches you described at the start of your comment (with multiple laptops, a gaming PC, and a homelab made up of what I'd call a reasonable number of physical computers of various descriptions), me and a few other friends of mine recently made the jump away from Windows and to various Linuxes on our gaming PCs.

I went for Ubuntu, while my friends mostly went to some type of "gaming-optimized" flavour of Arch.

I'm definitely an edge case as most computing goes, but it feels for the first time like the gaming-on-Linux train's gaining traction, and there's enough community support out there that making the jump feels like a palatable ideal.
