I use manjaro as a daily driver. At the time I switched to the distro it was perhaps the only accessible Arch distro and was highly recommended.

There does seem to be some stability issues (particularly in the boot/suspend logic/login logic), meaning that there are times where the system freaks out and will enable (for example) RAID in the bios. This gives a very disturbing recovery process, as a live-disk doesn't immediately detect that RAID is enabled and no drives are found by the bios otherwise, but the grub firmware remains in the boot-up process.

I wouldn't recommend Arch for all users, and the switch between AUR managers, packages etc is definitely some deep topics for most.

Personally I think Arch, even Majaro, is better than the Canonical path.
