I think much of what the BSDs offers can be achieved with Linux (and hardened Linux is probably just as secure), but it can be a lot more work and there is less guidance.
Locking down an Openbsd system is quite easy for example as it tries to have sane defaults. I find myself more in the dark with Linux.
Installing zfs on Linux is possible, but again can be a lot of work and it doesn't cleanly integrate with containers the same way zfs integrates with jails on Freebsd.
