The core system installs in couple of minutes and runs well on even the crappiest hardware.
There is not WTF stuff associated with runlevels (there are no runlevels).
You can find and install software by navigating a certain directory in the system and typing in one standard command. Great for feature discovery.
FreeBSD has the best documentation among all the software I have ever used: the Handbook, the help screens in the installer, the security emails, the upgrade notes.
