Let's just note here that this confirms my impression that the unnamed
Linux distribution is opitimised for new installations, whereas its older
relative puts more effort into testing that upgrades are handled in a sane
way (and, in my experience, succeeds quite well at that, too.) It also
does not try to release twice a year, but more like once every two years.
(Yes, the feature junkies won't use stable, but for those who just need to
do their daily work this works out quite well.)
