Gentoo - too long compile time, especially on my dated CPU. I prefer my system to update quickly.

Linux Mint - don't like apt, some packages I installed refused to work properly (like Lutris), and the color scheme which is admittedly customizable but I prefer rolling with defaults except when using WM.

Void Linux - after installing it I realized how much I actually missed systemd, couldn't be arsed to symlink services manually. And yes, I realize that's the whole point.

NixOS - realized how much there is to learn with the flakes and separating home configurations and whatever, and just gave up

Manjaro - I tried it twice at the beginning of my Linux journey, and both times the nvidia driver shat itself and gave me different problems that I couldn't fix.

Maybe I've been spoiled by Arch though, as most of my problems probably boil down to "not the same packages", "not pacman", "need to learn new skills that weren't in Arch" and so on. Though admittedly, I did try to explore with an open mind to find a new "cool" distro, but I'd always go back.
