If you are switching to a BSD for security reasons, why FreeBSD? Isn't OpenBSD the super secure one? Sorry, it's been a while since I've looked at those projects
I haven't switched to BSD but I've been thinking about it for a while. I just saw Vultr has both FreeBSD and OpenBSD!
The person suggesting FreeBSD is a FreeBSD developer (Colin Percival - actually according to Wikipedia FreeBSD engineering lead), would be weird for him to suggest openbsd.
