I kinda hate this take flying around constantly. There is such a thing as a gaming distro: one that has sane defaults for gaming, has the important things pre-installed like Feral GameMode, ProtonUp and the Nvidia drivers, etc. Also having an up-to-date package manager for these essentials is vital.
Yeah, technically all distros are very similar, but most people asking for recommendations specifically want something that just works for their task, not everyone can fiddle with packages and DEs to get what they want.
