Why not stay on arch? I doubt the experience with VMS will differ between distros, just try it out. And as others have mentioned if your concern is anti cheat than vms might not work since some anti cheats can detect them. If it is not anti cheat than any distro will do, since pretty much anything not anti cheat is playable through proton these days. Another thing to consider is your GPU, keep in mind that if you want to use it for gaming in a VM you need to make a passthrough and you won’t be able to use it for your Linux desktop (I think at least, there might be a way to unload the GPU at runtime, but it’s probably complicated)
