For someone who’s interested in getting into any *BSD, which should I go with? OpenBSD or FreeBSD?
I would say FreeBSD is somewhat like Ubuntu is to Linux - easy to get setup, works for more people.
There isn’t anything like OpenBSD in the Linux world - where the primary focus is system correctness, even at the cost of user convenience at times.
(FWIW, there several other *BSD's.)
Unless you're spinning up a MUD.
