I ran my college laptop through 15 system upgrades without any issues, nothing has been that reliable for me.
I’ve got a VPS running Debian Bookworm (12.0, latest version at the moment) that I haven’t reformatted since Etch (4.0, 2007). I’ve just done an in-place upgrade every time a new version is out.
That’s not a GUI setup though, so probably more stable when updating…
