I got tired of Manjaro breaking if you dare to try to automatically update it without reading the forums first to see what manual intervention is required. Also, since it shares a drive with a non-Arch-based distro, I got tired of the other distro's GRUB-configuration routine failing to recognize that Arch loads CPU firmware by GRUB instead of a kernel module and producing a broken GRUB configuration whenever I updated the kernel in the other distro. But I still wanted a rolling distro, especially since KDE is updating almost constantly. So I installed OpenSUSE Tumbleweed. It updates even more often, and more files at a time, than Manjaro, but has yet to break anything when I tell it to update everything. Most likely because SUSE has a bigger dev team with decades of experience.
