OpenBSD is a bit like Jazz music. When someone asked Louis Armstrong, "What is jazz?" his reply was, "If ya gots to ask, ya'll never know."
Though it will most definitely seem elitist, there's some subtle wisdom there; You need to experience it for yourself to learn the what's and why's. Similar is true for all of the BSD's. If you're just looking for a fast bullet point list and "executive overview" (a.k.a. "buzzword bingo decision support"), you'll never find a reason to run any of the BSD's, and worse, you'll never learn on your own why zealots like me exist.
The thing you're missing is the experience of learning it for yourself. You might come to a different conclusion than me, and that's fine, but you would still benefit from the experience.
