The last successful ubuntu upgrade I did was 10.04 (9.10 on my laptop), I think. 10.04 - 11.10 all broke (on multiple computers, in different ways) eventually requiring a liveboot and significant skill. (I'm now running arch, with significantly better results - but not perfect.)
I've never had an openbsd upgrade break, even when I do it the ninja way (which I often do, being a reckless fool).
Despite the longer setup time, I've found that openbsd servers end up needing far less maintenance than any others. It works well as a "fire-and-forget" operating system, a quality that seems to be lacking among the larger players.
(EDIT: not disagreeing that apt-get, yum, and pacman/yaourt are nice. Just talking about how awesome OpenBSD is.)

Note that apt-get isn't a supported way to upgrade in Ubuntu. You are supposed to use "do-release-upgrade" (or "Update Manager" in the GUI).
do-release-upgrade is how I did it - but it really just does apt-get underneath.
