I find OpenBSD much easier to manage than most Linuxes, where everything changes every six months for no good reason. Then again, I have 30 years of UNIX experience.
The main reason to avoid it is the limited hardware support, specially for laptops. I wish there were an equivalent of System76 for OpenBSD.
Having a ThinkPad X230 in daily use with OpenBSD, have to say it's an excellent laptop and everything just works. Even the WAN, which can be turned on using `ifconfig` and is handy in places with no wifi, such as the country house.
