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.
