If you’re interested in why some users have FreeBSD as their operating system of choice, this thread from /r/sysadmin documents a bunch of pros and cons from system administrators all around.

The top comment reads:

  • zfs
  • better networking implementation
  • jails
  • having a single source for everything (as opposed to kernel vs os)
  • the ports collection
  • the bsd startup system
  • the freebsd community

Some people may NOT prefer these, but others do. It all comes down to preference and what you are using the system for.
