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.

Unpopular opinion: snap is not so bad and genuinely useful for many things

I would rather have a snap than building from source or use some tar.gz archive with a sketchy install script
