I love OpenBSD because it is as close to "just works" as it gets in an ideal world. I love using it for my personal website because it is very easy to get a proper overview over the OS as a whole and because it comes with some of my favourite pieces of software and all I need for a personal website is part of the system: httpd, pf etc. Also OpenBSD has some of the best docs out there, I rarely need to websearch anything.

Unfortunately, we don't live in an ideal world, so I rarely get to spin up OpenBSD outside of that due to a number of reasons like a lack of filesystems for interoperability (USB media) and firmware drivers (got to be specific in the hardware you buy for it).
