I don’t even want to hate on Snap, I just think Flatpak is probably superior in almost every way and it’s probably not great that there are three competing formats for “applications with dependencies included”. It was supposed to be “package your app to this format, dear developer, so everyone can use it no matter the distro they use”, now it’s a bit more complicated. Frustrating, as this means developers without that many resources will only offer some formats and whichever you (or your distro) prefers might not be available.
I know that you can get every format to work on every distro (AppImages are just single binaries you can execute), but each has their own first class citizen.
By the way, the unofficial Steam Flatpak has been working well for me under Fedora 39 KDE Spin, but an official one would be great to have.
