I see there's some sort of "how's Linux now" discourse going around Mastodon and so I'll give my brief summary:
To be blunt, Linux is just the least-shit option to run on your PC nowadays lol.
If you want a good start, try Kubuntu https://kubuntu.org/, I get along great with it. Familiar interface, without all the shovelled shit Microsoft constantly try to force on you. Same KDE Plasma interface Valve use for Steam Deck's Desktop Mode.
Even if you last tried Linux say 2-3 years ago properly, it's quite a different world. Thinking on the rise of Flathub / Flatpak, getting apps is so much easier now across nearly any Linux distribution: https://flathub.org/en
That's one thing I thought we were missing some time ago, that is close to solved now.
Valve Proton has made gaming close to solved too. Most single-player games work great, but anti-cheat remains problematic.
Almost everything I play is really smooth. Hilariously, my Windows 11 install runs games worse somehow confused. And I've done basically no tinkering to my Linux install, I use almost all defaults...
