I feel like both Snappy and FlatPak are inferior to AppImage, which IMO is much easier to use (it's a self-contained executable) and doesn't rely on any fancy management daemons or what have you. Like, in terms of user experience it's about as close to the Windows-style "download this .exe and run it" approach as one could get, though it'd be interesting to see a macOS-style "put this .app in your ~/Applications" approach as well (which should be doable with a daemon watching such a folder and generating e.g. menu entries and such, as an optional component or perhaps a feature of the desktop environment itself).
