I'd rather have debian stable. At least the packages actually work. Ubuntu is so damn unreliable (even LTS).
I would have disagreed with you until a few weeks ago. The past few updates have been requiring us to restart our servers. You restart it and a day later there is another update that requires another restart. Putting off updates on production servers is no longer a choice but having them now is not the best thing either.
The issue is versions being pinned on LTS packages to broken versions. This includes svn, MySQL and a notable gcc problem which is a PITA.
