I've found that dist-upgrade in Ubuntu introduces lots of breakages in Ubuntu. Was workaround was to reinstall keeping /home untouched. Once though, because of some UI/UX problems with the installer, I ended up formatting most of my /home before I aborted the install. That was the turning point for me. I went back to Debian and haven't moved away since.

Opposite of my experience. Been upgrading from LTS to LTS in production for many years. Non-upgradable OS like Windows and Suse Linux used to warrant new server hardware, but now the servers live far too long since there is no need to migrate.

You said production so I'm assuming you are using server version.

The vast majority of issues I was having were around desktop functionality: connecting a monitor to laptop, weird issues with UI, wifi, putting laptop to sleep. Actually one of last issues that infuriated me was them being ok with release that that crashed (froze) every time you started a laptop with a proximity to 802.11n network.

Imagine trying to use your laptop to take notes in college and it froze few seconds after it booted up repeatedly. It took me a while to find out what the problem really was, then found the bug, realize that it was opened before the release, yet they still went with the release.

To make things even more frustrating at the same time they refused to include OpenOffice 3, because it might not be stable enough. Talk about priorities.

That was the time I started looking at alternatives, someone recommended OpenSuSE and I really liked it.
