> it is actually a good experience to run Linux on the gaming laptop instead of Windows

Not a laptop, but I am livestreaming games from a Linux desktop. In the roughly two years since I've started doing this on a regular basis, I have played 23 games on stream using Steam Proton. My experience matches what Steam Deck owners told me about compatibility. It's not been completely glitchless, but all the problems I ran into were minor graphics glitches. When I buy games, I check protondb.com in advance, and it's always either Platinum or Gold for me these days.

I will note though that all the games I played were either single-player or cooperative multi-player. With competitive multi-player, there is an entire can of worms because of anti-cheat software. Valve's own anti-cheat should be fine, but if the game developer is using a different anti-cheat, it usually relies on Windows kernel drivers or some other shenanigans that conflicts with Wine in a major way.

A surprisingly big number of anti-cheat games work on Proton:
