Theo de Raadt is a great guy. He gets a bad rap when it's undeserved. What the OBSD guys is very serious stuff. He gets a lot of flak but running an OS and security software project as successfully as he does takes a strong personality. He has that, and in the real, he's a nice, friendly guy. He simply has no tolerance for people with no merit and nothing to add. Anyone would be the same.
I've met a couple of snarky FreeBSD admins, but they were also Linux and Windows admins at the same time. These two guys were full of themselves regardless of platform.
BSD (in general) tends to be more polished than Linux and suffers fewer bugs out of the box. Again, this is what I've noticed. I've yet, in almost 20 years of using FreeBSD off and on, ever had an issue with it that was a deal breaker. I cannot say this of the various Linux distros.
