Small question, but calling for big answer ;-) I certainly am not as knowledgeable as Steve O'Hara-Smith is. I just would add Linux refugee prospective. Over 5 years ago I started seriously looking which system to migrate Linux servers to. The reason (one of them) was: on average you have to reboot Linux every 45 days. There is either kernel update or glibc update, so you have to reboot. Compared to that FreeBSD only has updates requiring reboot about once a year. Recently there were other big turns Linux took which very many who use Linux dislike a lot (systemd, firewalld, and friends). This can be considered question of taste, but for me that just confirmed I was right when decided to flee servers to FreeBSD. My favorite CentOS Linux (aka binary replica of RedHat Enterprise) became more like MS Windows, and farther away from UNIX IMHO. Good luck making right choice. You can install two systems on the same machine, and start using both, then you will make your own choice based on your own experience. If it is server I would strongly recommend FreeBSD (or any of close relatives like NetBSD). If it is workstation, it may be simpler to install FreeBSD based TrueOS (formerly known as PC_BSD). I, however, preferred a bit more works and have FreeBSD on my workstation and on my PC laptop. Steve mentioned FreeBSD handbook. I would say, FreeBSD is the best documented system IMO.
