It's true that drivers might require a bit of fiddling, but if your hardware has been around for a while you'll probably manage.

I'm quite fond of OpenBSD. It's such a nice, wholesome Unix experience. The man-files are great, typically you can get by on those if you mess up and lose Internet connection. To me it has a feeling of being rock solid, like it'll never break. Common programs differ a bit, pkg_add rather than apt/RPM/pacman/&c., you'll probably use pf rather than ufw or iptables, vmm/vmd rather than Docker/jails, flags on some everyday terminal tooling work differently.

Some software just isn't available due to it being considered insecure by the OpenBSD community or its 'dictator for life'. As a C developer you might run into such constraints.
