OpenBSD is top of the line when it comes to security, stability on supported hardware, consistency, and coherence. The entire distribution is taken care of by a single team. Security is a higher priority than additional features. Documentation mistakes are considered bugs that need to be fixed. Minimal surprises. I got deep into router implementations like we are talking about years ago, combining ipsec, gre, bgp, and qos, lots of end-points and queues. OpenBSD had more features and less bugs in this space than cisco routers at the time. I was very impressed. Like so many other things, it may depend on what you're doing and what you are comfortable with.
