I also like how I can basically change everything in Linux from icons to mouse cursor, to basically force dark mode in any app whatsoever, or theme. I can have coherent menus, if something is dark themed I right click and the menu list is dark themed also. Lmao.
Even exe files I run under Wine/Proton can run with dark outlines, something which absolutely pisses me off on Windows. As my PC monitor can get as bright as a sun in both HDR and SDR. And sometimes late at night similar apps in Windows burn my eyes out, and not on Linux. There's some peace in that also that you can tweak what you basically want and it's not that hard to do so also, so it's not like you have to sit at it for hours lmao like some would want you to believe.
Be sure to install TimeShift and use it, it will save you a lot of headaches.
Another distro I would recommend after CachyOS is Nobara. I think you can basically just let it autoinstall everything for you. And it can do so also with Nvidia drivers. Could be a nice first experience with Linux as you won't have to touch terminal at all. It also uses CachyOS kernels so it will be nice and secure distro with top-notch kernel improvements. Also GloriousEggRoll is really helpful if you have any issues they will try to help you in any way they can.
FYI OptiScaler just works on Linux so you can use DLSS all you want.
