I wouldn't take it personally. Ubuntu made a specific effort to improve the Linux end-user experience, and they've pretty much succeeded. In the process, their rapid rise to popularity has pushed a bunch of the other distributions into making their systems more homogenized, so Linux has really gotten a lot better for the end-user in the last decade.
That said, OpenBSD is probably the most organized project out of all open source projects close to the same size and scope. They release like clockwork, they do not (or try not to) rush new features out just so they can make the next release, and there really is an uncompromising drive for perfection.
I would love to contribute code to the project, but I have to be honest: though I'm by no means a slouch programmer, those guys seriously outclass me, and I'd be completely out-of-my-league.
Having perused bits of Linux source from time to time, I don't feel that's so much the case outside of OpenBSD.
