Gnome user here.

No LTS, they support each version for 1 year, and there are two major upgrades per year. I still haven’t upgraded last October.

But I never had an issue, I always upgraded using the terminal instead of the GUI.

I’ve been using Fedora for the last 5 years and never had to reinstall the OS. I’ve been upgrading with no issues whatsoever.

With Ubuntu, I had to reinstall everything on every update because of errors. Not on EVERY update of course, but often enough to make me want to stick to LTSs.
