At this point, I have been using CachyOS as my primary operating system for months. I kept Windows 10 installed at the outskirts of my SSD, just to be safe--but so far, I have only booted into it once or twice to test out just how much better Unity runs on Windows than on Linux. The answer seems to be "a little bit better". The main issue is fractional scaling.
Considering how much I fell in love with Cachy, especially because of how eager I was to learn the ins and outs of Linux, I decided to find some time to install Arch Linux manually on at least one device. One almost sleepless night later, I had a functional system. Another afternoon later, I had Niri and KDE Plasma running, and the damn thing felt like I brought it back from the dead. Now I can say that I use Arch (btw).
