It's been fairly stable as I would expect from an LTS. There's LOT of hiccups with whatever is happening in the tray area (power and battery sometimes doesn't work).
Language is pretty screwed up. I speak both English/Spanish in a Spanish location. Installer chooses half spanish and english in the /etc/locale, and has issues changing it in the frontend.
Overall nothing I can't fix as I put stability overall
Good on ya! I’m still hopping from time to time, but for me it’s quite simple as all my most needed data is on my server. So don’t have to worry about transferring stuff. I’ve yet to try KDE neon, but it’s on my list 😊
