I built a new computer recently (it is now my pride and joy) and installed CachyOs instead of Windows. Cachy is based on ArchLinux, but with modifications to streamline the process of installation and make it easier to run video games.
I guess you could say that I'm an Arch user now, but I don't know if I want to be put under that umbrella...
Anyways, I've been using Cachy for a few weeks now, and I've been liking it a lot! I used my Steam Deck as my daily driver for about a year, so that has given me an upper hand when it comes to learning how to use Linux. The Steam Deck uses KDE Plasma as its desktop environment, but I opted to use Cinnamon for my PC. KDE is great, but I've been enjoying the slightly higher customization of Cinnamon. Cinnamon is very "set it and forget it," so when I finally figured out how to apply the icon and desktop themes I wanted, it was pretty much perfect for me. Any GUI app that I install follows the themes I have set, and it's great!
Compared to Windows only in terms of UI design, using Linux looks way better. Each window consistently follows the same theme. Only occasionally will I use a program that doesn't have the theme set correctly, but it is still far more consistent than Windows. Microsoft hasn't changed a slew of system dialogues to be able to match to the user's selected color palette, such as the environment variables and control panel windows. They still have an outdated, off-white theme that grinds my gears every time I (used to) see it.
One thing I sort of miss from using KDE is the Discover store. Cinnamon doesn't come with a GUI package manager (it comes with Octopi, but I just ignore it because it only looks for system packages), so I've mostly been sticking to the command line. I'm comfortable at the CLI, so it hasn't been bothering me too much. I have to manually install system updates every so often, and I do have to look up the names of packages, but I still enjoy using the command line. I like how Linux handles everything for me, instead of having to download executable files for every program, like you do on Windows.
Gaming has been basically the same as it was on my Steam Deck or Windows. For a while I was concerned that my GPU wasn't being properly utilized, but my suspicions were quickly dismissed when I saw that Cyberpunk 2077 was using the 16GB of RAM available on my GPU. I think it just seems a little iffy sometimes because my GPU is a very new one, the Radeon RX 9060 XT. I can still run games with it, likely thanks to the CachyOS developers' hard work.
Overall, I'm super happy with my new PC and my Linux experience. I think it's only going to get better as the software improves and more people start to switch. If you're going to be building a new computer soon (or you're swapping from Windows 10 to 11), consider using Linux!
