Not really, but OpenBSD has been in my life for 25 years.

I used OpenBSD to create the firewalls for our LAN parties when I was at school.

The first shellserver I ran, on an UltraSparc IIi was OpenBSD, gave out accounts to my friends.

And then I used it as a firewall, both professionally and personally, for many years. Until the first Turris Omnia was released, and now I have retired even Turris for pfSense, which is FreeBSD I believe.

But the PF firewall in OpenBSD was superior, definitely to the syntax of IPtables.

To me Linux was a great server OS, and OpenBSD was a great FW/Gateway OS.
