Particularly if you want to play with a controller (as is common for a living room/couch setup). Windows somehow has the worst controller support out of all operating systems (including mobile OSes) and if it weren't for Valve patching things up with Steam, it'd be almost unserviceable in that category.
I just don't undertand how Microsoft puts up the pithy 'Game Bar' and calls it a day. Put up a proper entertainment center UI for Windows that integrates stores, I shouldn't have to install Playnite or anything, which has its issues. Make it optional like PowerToys if you wanna be unrealistic about not 'cannibalizing Xbox sales' or some such nonsense. I should be able to game from any store or pop open Netflix without dealing with Windows 11's UI at all.
I've been struggling with both Linux and Windows gaming.
Windows gaming is unstable AF, games crash, peripherals don't work, wifi and firewall issues galore. You won't know until you install all 160 gigs.
Linux games work when they work. If its linux compatible or runs on Proton, you are fine. However, not all games are like this. Your favorite 22 year old game, probably wont run, even with proton.
