Well, I fled servers from CentOS to FreeBSD almost a decade ago. And

Just straightening small nuance.
If you aren't rebooting your FreeBSD systems regularly, you're just as
vulnerable.

I see one less than 45 days ago that requires a reboot because of a
kernel security measure bypass.
Long uptimes are a thing of the past. Build redundancy into your
infrastructure so you can handle reboots.
That original reason to flee for us (one of several as it turned out to
be) is dated 10 years back. Not quite fair to apply today's
counter-argument to it. Still a year or two ago when I checked last, and
it was about 2 reboots a year required for FreeBSD, whereas <= 45 days
is still was a fact for Linux.
But as you have said yourself, we live differently today, and several
things (like one or few services per jail - the last having read-only
base system to mention one) still make FreeBSD much simpler to maintain
for servers. Not to mention, switching from Linux (10 years ago) to
FreeBSD was quite smoother learning curve than adjusting to systemd and
friends ;-) (I'm cheating a bit: I did run UNIXes in the past - waaay back).
Of course, tastes differ, but still, only those who tasted both things
can have fairly say what is better to one's own taste. Saying not to
Jonathan, of course, who I bet runs several UNIXes, FreeBSD included.
(of course, not all of them can strictly be called UNIX, - re no
loyalties to AT&T).
But even as part of our infrastructure fled to FreeBSD, workstations and
number crunchers stayed with most adequate for them system: Linux.
CentOS until recently, Debian once CentOS stopped being "binary replica"
of RedHat Enterprise. Gionatan Danti mentioned another important reason...
