I use Arch because it's so customizable and there's so much more freedom. Once I installed Arch I realized I'd never go back to Ubuntu. I'm so used to using the command line all the time now it feels weird and annoying when I have to use something with a GUI desktop environment (I use i3.) People always tell me when they see my system in public (it's a ThinkPad) it looks clunky, but even the inability to set custom time/date settings in KDE was mildly annoying to me.
I sincerely think CLIs and TUIs are no harder than "user-friendly" GUIs but they're just too far from the average modern person's experience for this to be acknowledged. Using nmtui to connect to WiFi is hardly more difficult than what Windows or macOS do.
I also really love pacman, the AUR, and the Arch Wiki.
