Most reviews are very positive. Faster, better, Amazon removed, maybe the best Ubuntu release until now. The only 'con' is the pushing of Snap packages. It looks like deb files only can be installed via the terminal. Ubuntu is also researching if they can get Adobe on board. I doubt this would ever happen, but that would be huge. Most people stick on Windows and MacOS because Adobe software is not available on Linux.…
It makes my system less predictable, increases load times, makes UI stuff look ugly, obfuscates process monitoring, hogs memory, cannot deal with files in /tmp (and I happen to use /tmp a lot), makes if hard to do audio (like connecting a mic to Chromium)... I can go on.
But in 2019 versions of buntu it could still be removed:

I found a way to use Debian packages reliably on buntus with a trick that is shown here for Chromium:

If this snap thing continues to invade the *buntus I will move away from them. For now I still like the combination of stable + up-to-date + familiar (Debian based), but --as others have said-- the snap thing goes against why I choose to use open source.
