Not who you originally asked, but I am aware of an example where Windows is still better than Linux for a specific game: Guild Wars 2. Not because of anything directly in the game, but there is an insanely useful overlay program called BlishHUD that runs as a separate process. On Windows it just works; on Linux it is a pain to get it to mostly work.
But overall things have clearly shifted from gaming on Linux being a joke, to being possible but a huge pain, to being ok-ish but a bit clumsy, to finally being sometimes even better and on average equal. There will always be differences, and Windows currently still has the benefit of being the default. Maybe that too will change one day.

GW2 gamer here too, I’ve been switching over to Linux over the past few months and this is on one of my to-do lists(figure out HUD/overlay software for GW2).
Another hurdle I’ve had is getting mod support. For example, Tale of Two Wastelands. The standard installer is exe only and it runs via proton but it doesn’t use all CPU threads to decompile the game assets. Takes over a hour to do. Luckily someone was able to build something that fixes this for Linux, takes 10 minutes or so depending on your CPU: github.com/SulfurNitride/TTW_Linux_Installer
So I’m sure something is also available for GW2
