I think I've landed on Flatpak as my favourite between Snap, Flatpak, and AppImage. AppImage, when it works, is nice though. Snaps are just kind of inconvenient (auto-updates are a no for me) and bloated and the things Canonical are doing as an organization put a bad taste in my mouth.
I’ve had bad experiences with AppImages. For universal format they do a really poor job at that. And it’s a huge step back into Windows direction that you’ll have to manually download, update etc your shit. Makes managing a bunch of apps a pain.
The thing with appimages is that they expect the developer to have full knowledge of what libraries need to be bundled with their app, which makes it difficult to make truly universal appimages. In flatpak you just select one of a set list of runtimes and add any additional dependencies on top of it. Flatpak also re-uses the files for each runtime in between the different apps that use it, which saves a lot of disk space.
