@shawnp0wers I would say Flatpak becuase it is not as vendor-related-controled as Snap is (by Canonical). Flatpak is at least for Linux Mint well integrated to their software manager. I have not tried Snap. But I think Appimage is the one I like most; I download one file, make it executable and that's it. But this is when its relatively few, if all applications on my machine would be container-based, at least I should add sw for Appimage-maintenance. Elementary is interesting using only Flatpak.
