To be fair if you set it up properly, you don’t install a ton of stuff from the aur, and you stick to a major desktop like kde or gnome it’s stable to the point of being boring.
I’ve recently switched to hyprland from kde just to have something to mess with or tweak when I feel like it. Sometimes they change the config file for hyprland and I have to fix it but I like it none the less. I used kde for a couple years with zero issues and only just switched desktops using the zx backdoor as an excuse to while my system.
This is coming from an individual that hasn’t had an opportunity to switch from an Nvidia card yet.
