The chromium transition from deb to snap has been discussed here (Note: October 2019)

https://snapcraft.io/blog/chromium-in-ubuntu-deb-to-snap-tra...

Ubuntu could not maintain a deb package, and keep it up to date. Therefore, there is only a snap package. When you try to install with `apt`, you get chromium installed transparently instead of getting a message that describes what I already explained. The breakage would be bad if there was nothing installed when you did a "sudo snap install chromium-browser".

AppImages are monolithic images, with no or minimal protection of your computer. I think they are the equivalent of the Windows packages in the 90s and 00s, that were distributed with CDs with little idea where they came from.
