Each of the BSD's have their own personality and group of adherents. There is a secondary circle that may love all BSDs. Long ago there was east coast unix and west coast unix. The BSDs represent the West Coast thread.
I just like the BSDs because they all maintain a single document that can get you from a single system host install to a supporting network installs DHCP->TFTP install.
I always go for either NetBSD "We install on anything" or OpenBSD "We are still just trying to get secure implementation of the 4.4 spec"
Unlike some other operating systems, OpenBSD encourages users to split their disk into a number of partitions, rather than just one or two large ones. Some of the reasons for doing so are:
• *Security: Some of OpenBSD's default security features rely on filesystem mount options such as nosuid, nodev, noexec or wxallowed.*
• *Stability: A user or a misbehaved program can fill a filesystem with garbage if they have write permissions for it. Your critical programs, which hopefully run on a different filesystem, do not get interrupted.*
• *fsck(8): You can mount partitions that you never or rarely need to write to as readonly most of the time, which will eliminate the need for a filesystem check after a crash or power interruption.*

Really no idea why it insists on splitting it into 5 partitions when just a seperate /usr/local mounted with the wxallowed flag is mostly fine.
Other than that though it's mostly just hitting enter a bunch of times if you ever want to give it a shot again.
