Didn't say they were equivalent, I've said Borg is enough for me, specially when pacman does a very good job updating the system atomically. In the rarest cases where a pacman update breaks the system, which is usually when the user doesn't have informant installed and forces a failed installation, I'd just chroot from an arch live install disk and fix the OS.
