Linux is a depressing mess after you've used OpenBSD. Such a high quality system, with stellar documentation. It's unfortunate that Linux has become so popular even though the BSD's are so much better. A bad historical accident. Damn you Linus...
OpenBSD is great, of course, but my favorite thing about open source is the cross collaboration. Rather than dump literal decades of constant refinement to Linux and it's ecosystem because OpenBSD is much more elegant seems unwise. There are things Linux and the general Linux stacks could learn from OpenBSD (and should.)
I don't think the world would be better if OpenBSD were in the position Linux is in today (though I have a hunch the security story around FOSS stacks would be better.) I think there is a lot of good that Linux can do with its more fast-and-loose organizational structure.
