As someone who has used FreeBSD exclusively on bare-metal corporate production servers for the last 10 years, I still wouldn't use it on desktops/workstations. It's built as a server OS and my opinion is that it does this very well, I have tried a few times over the years to use it as a destkop OS, I spent more time configuring my machine than I did actually using it. I can install Ubuntu and 30mins later be using it for work with no issues.
If you run your own servers, especially ones that you physically have to maintain the hardware on, FreeBSD is a very reliable choice and the upgrade paths on it are fantastic. I now run some services in Azure and use docker, but all my "on prem" stuff, is still freeBSD powered.
OpenBSD is often considered the desktop BSD. You install it and it works or it doesn't. The only real hangup tends to be configuring the sound if you want to do something different but once you get it configured that configuration is forever and solid.
Yea, I have tried OpenBSD a few times, but sadly I just don't have enough time to invest in my OS to get the most out of it. I use my machines until they fail, then replace them with a new one/part. A fresh install of ubuntu and they are ready for work in 30mins. I used NixOS for a small period of time for this reason, but even this became more of a headache than it was worth.
