It looks like this page isn't quite finished yet, but it looks promising! I may want to try OpenBSD one of these days. I have at least one friend who loves it and constantly tells me about how cool it is compared to Linux.
It a matter of preferences. Linux is hard to beat, but so is macOS. OpenBSD is cool in its own little ways. For me it's the consistency and ever present documentation. FreeBSD fans will say: "FreeBSD has a the handbook, and it consistent", but it is not the same, it's not like OpenBSD. In terms of consistent feel (command line, documentation and system configuration) FreeBSD feels very much like someone made an effort, OpenBSD feels like they succeeded.
While OpenBSD can be a great desktop, even if it does require at little more tweaking than I care for. It's almost there, like an older version of Slackware.
For me personally, it's macOS desktops and OpenBSD servers, if possible.
