Ubuntu is nice. Apt/DEB works as they should. Some default apps, mostly browsers, are snaps now, but this does not bother you at all. You were getting them from your distro anyway.
Flatpak and AppImages work just fine if you need them.
The Ubuntu desktop (any flavour) just works. Others are different, but nothing is bad about Ubuntu.
Ubuntu is trying new things, proprietary to their ecosystem, e.g. Unity or smap. On the big picture, those are experiment. Ubuntu is still Linux.
The community reaction to snap is overblown. So Canonical developed something you don’t like? Ignore it. This has mostly been a waste of time for them.
(Yes, maybe that dev time would be better soent on flatpak or open-source apps. But that’s their time. I’m not paying Ubuntu developers, so can I really complain?)
