I wouldn't go that far: I've had issues with every major version upgrade so far and I've been using Linux for over 25 years. My experience with Ubuntu has been a bit bumpier with Ubuntu than other distros on desktops in particular. There's always at least one driver (or default) that has changed just enough to break something requiring research to fix and usually a couple of packages that have been removed from the repos. So I always figure on an afternoon to deal with any immediate (i.e. booting) issues and a bumpy few days as I have to work out any substitutions.
