I have used all 3 major BSDs (Free, Open and Net). FreeBSD is ideal for servers due to its performance. OpenBSD is perfect for security appliances and NetBSD is perfect if you have exotic legacy hardware.
Funny that those descriptions contradict what these Distro actually aim to do. NetBSD is a the supposed performance oriented distro. FreeBSD should be able to do both, desktop and server. But your are on point with OpenBSD.
