Those are some serious claims that are not at all objective. I can tell you that I have found OpenSMTPD to be at least as inelegant as just about everything else that touches mail, and PF is a good design but has always had serious competition from the commerical world.

I mean, I love OpenBSD too, but you can't drink the Kool-Aid like that. It's got just as many design tradeoffs built in as any other competent OS.
