My experience is limited, but I really liked it. Didn't end up sticking with it for very familiar reasons - lack of http3, third party shitware that it's sometimes convenient to have for work, hardware support. But as a pure OS I thought it was miles above linux. Things fit together so well. And the docs! First time I'd ever read man pages so good that I took notes.
In an alternate reality, where Linux was an obscure OS and OpenBSD got all the love from third party vendors, driver writers, etc - the world would be a better place.
