I like OpenBSD a lot, but I have to nitpick your description: OpenBSD diverges from "standards" when they decide the standard doesn't make sense. They are not afraid to tear down working things when they decide it's necessary, and I've faced a lot of release-to-release breakage, forced reconfigurations, or features I've relied on go completely missing without a lot of warning.

Still a great project that I use every day, I'm not knocking it. It's just not a great example of a change-averse type of stability.
