It's been Year Of The Linux Handheld for gaming since 2022, the best platform to play games is Steam Deck where updates are clicking "Update" in the System panel. You can run either Bazzite or SteamOS on your own hardware, although I haven't tried that.

The best platform, provided the games you want to play actually work and work well. Many do not, even some popular ones.

I own a steam deck and love it, but please, let’s temper the enthusiasm with realism.
