I can't comment on FreeBSD, as I've never used it (I believe it's about
equal to Linux and NetBSD on terms of security). However, I've been using
Linux since 0.12, played with NetBSD years ago, and have been running
OpenBSD for a couple months now on one of my systems.

There is a program called 'saint' which is a offshoot of 'satan' I believe,
that you can use to test your systems security. I ran it against my
primary Linux box and then ran it against my OpenBSD server. Both running
pretty much out of the box, the Linux box was running Red Hat 5.1 and I'd
added a lot of stuff, but no real security changes. The OpenBSD box was
either 2.3 or 2.4 and totally out of the box. 'saint' found a LOT of
problems with Linux including a couple serious ones, there were two
warnings on the OpenBSD box, what were they, I had telnet and ftp turned
on. Linux on the other hand had all sorts of stuff turned on by default
that I didn't need or want, but had just never bothered to turn off.

Basically for a day-to-day workstation setup I'll run Linux, but if I want
a fairly secure box, I'll run OpenBSD, if I want a really secure box, I'll
use VMS. Consider this, I don't really like BSD, and am a major Linux fan!
