OpenBSD it's much easier to setup than NetBSD, on user friendlyness obsd beats nbsd, but as you said nbsd it's better on portability, I can literally run NetBSD 10.1 under simh/vax running under... 9front. No X, because the emulated ethernet in the port of simh here just simulates nat with no option to bind it outside, although I didn't test it further. But for sure it runs at decent speeds, almost like an emulated Pentium 90, enough to run Slashem under vt(1) (vt100/220 emulator for 9front).
