I run OpenBSD on my router.

t's very compact and simple and you don't need Google to solve problems because the base system is thoroughly documented.

It has everything I need, and nothing more.

OpenBSD isn't suitable for every use case because rarely used features tend to get removed instead of falling into disrepair from lack of maintenance, but when it does work, it works predictably and reliably. I was able to run OpenBSD on my desktop and have everything work flawlessly out-of-the-box, whereas with FreeBSD I encountered frequent crashes when using dual monitors. I suppose my configuration isn't something that the FreeBSD developers use, so while it "works", it doesn't work.

In the end I returned to Linux because I sometimes play games using Steam and Wine, neither of which is likely to ever be supported on OpenBSD, but if OpenBSD provides everything you need, it's certainly worth trying it out.
