Not theoretical. We have people in the electronics group who
already use/always did use FreeBSD.

For historical reasons we (I) have been with the Red Hat linux
since late-1990ies, but I came there from SGI IRIX which was nominally
SYSV but all the good parts were BSD UNIX.

Vendor support for FPGA devices and ARM CPUs is presently with Linux,
but this does not preclude hybrid systems like BSD userland running
on a vendor-supplied Linux kernel.

On server/desktop this there is even less difficulty switching to BSDs
so long as they come with "can run RHEL6/RHEL7 applications" compatibility.

Historically, Linux had the best networking and the best memory management,
as features required for data acquisition work, but I understand FreeBSD
has been much improved, ZFS-on-FreeBSD is supposed to be the best
storage system obtainable. (The worst is the MacOS kernel, firmly stuck in 1990,
does not even have sem_timedwait).

Many Linux-only features (selinux, systemd) seem to work opposite to "stay with linux".

K.O.
