What @ricky89 reported about Rolling releases gives you MORE confidence to run one of the most bleeding edge distros? 
@shybry747 I respect you for that!! 
About 4 or 5 years ago, I still had that faith.
OOn a serious note, I think Arch really helps us learn the inner workings of Linux better than probably any other distro (close would be Slackware and Gentoo).
They don’t get caught up with all the fancy atomic updates, or try to reinvent of replace stuff like their package manage pacman, or AUR or anything that they have spent the past 20 years building on.
That is part of what makes Arch Linux so great and unique! Much like Debian they have stuck to their roots. No matter how many years pass in between, you can always circle back to Arch and know what to expect. That in itself adds a level of stability.
Talking about it, I think I will move Arch ahead of Manjaro in that stability list. Manjaro is constantly changing, lol. At this point Manjaro should just consider becoming an independent distro.
