I've run OpenBSD in the past, and I think they do some good work, but I sure do steer a wide berth around all of the politics involved. I kind of agree that their focus is a bit too narrow. When it comes to the BSD world, I think FreeBSD is sort of the best of both worlds. They're more interested in supporting new hardware and improving performance, and the fixes for security holes that the OpenBSD folks find usually get ported over. One thing to keep in mind when comparing the BSD security model to Linux's, though, is that the various BSD distributions make no claims at all about the security of anything that isn't in the base system. They don't do security notifications about problems in other software (the "ports tree"); you're expected to keep track of those packages yourself. Linux distributions tend to take a more supervisory role where they track the security status of everything they make available.
