It just works. No need to sift through dozens of config files and options and issue a hundred verbose commands just to get the system in a somewhat working state. All my laptop's buttons work correctly out of the box. And it didn't even come at the cost of sprawling complexity maintained by a patchwork of corpo patrons, underpaid code monkeys, and forum users. The system just fits together very well. The documentation is amazing too.
Easily my favorite Unix. If Linux was too complicated or barebones for you, give OpenBSD a try!
The biggest out of the box difference on desktop is that openBSD has a working X system and session manager out of the box. It's a very bare bones ones, but it is there. Freebsd is a fully functional CLI system post install. Setting up a GUI is simple, just not pre-installed.
