Same. My first Linux was Ubuntu 9.x, every time I upgraded the major version something broke. Eventually ignored the "Arch is unstable" as I saw my co-workers having zero issues, and been using Arch since 2017 now with zero breakages that I myself wasn't responsible for.
Same here as well, using arch as daily driver for 10+ years now. I think just twice I've had major headaches due to package/kernel upgrades which required a few hours troubleshooting. Otherwise, smooth sailing and a pleasure to work with. Love the AUR (w/ pikaur)!
Never heard about pikaur before (Rua gang here), but judging by the screenshots, does it not allow you to review the PKGBUILD before building the package? Seems to me like the most basic feature a AUR helper has to have, since AUR is all user-contributed without reviews. Is pikaur really letting you install packages blindly like that?
