I have had a long relationship with using Windows and Linux. First off, many years ago, Ubuntu. Before Snaps. It worked well, but compatibility with stuff is very limited. Good for a web browser PC, not good for the daily.
Lubuntu was my go to for a long time, LXDE was a very light desktop and the whole desktop would take 150-300MB of RAM, where Windows took 2-3GB, and even Ubuntu took 600-800 MB (which was a lot ten years ago).
I'd tried many distros - Slackware, Fedora, Mandriva, Ubuntu, Linux Mint, even used Manjaro for a few months, but at the time, the same problems were always present - limited support for anything. Nobody had working GPU drivers in the kernel - all were fb basic drivers that didn't give you much if any hardware acceleration. Nvidia was proprietary. ATi was proprietary. Their drivers required specific kernels, and would break on anything else. Ditto Intel. Wireless drivers were almost nonexistent. Laptop power management was nonexistent. X Window System is a spaghetti monster.
I'd wanted to Linux for a long time, but these road blockers have always been a problem, and thus I kept running Windows, optimizing it to the 11's to keep it running smooth.
Enter Valve.
Their real attempt to run games on Linux via Steam Deck, and all the supporting work they did to make that happen smoothly was a game changer. Now, AMD has an open source gpu driver built into the kernel, so does Intel. Nvidia also, but their open source driver needs to cook before it's actually useful. KDE has a good desktop environment ecosystem now. Proton lets you run almost any game in Linux at native performance.
Early this year, I went all in on Fedora when PCVR Streaming became a working thing. Now we have flatpaks to eliminate the distro release problem. Now we have good drivers - so good wireless pcvr works better in Linux than in Windows on the same system. Linux kernel even has seen a huge upgrade in performance and reliability in part due to this shift, and especially the valve programmers that have made even the old amd graphics drivers work more reliably.
The big difference is, where Windows 11 takes 5-9 GB RAM at the desktop, a similar setup in Fedora (startup apps and stuff) takes 1-3. That's a big memory budget savings if you're pinched for RAM.
Now why Fedora KDE and not Arch, CachyOS, or another focused distro? Fedora combines the traditional setup with flatpaks, and they do put effort into making sure updates don't set your PC on fire. Normal people can use it. It has all the features you're looking for in regard to general use.
