In my experience, snap is Just Bad and will probably disappear in the next few years like all of Canonical's other NIH projects. Software availability is kinda ok, but compatibility and functionality is all over the place, primarily I think due to the sandboxing. Though, even classically confined snaps will sometimes misbehave in weird ways. E.g. for me, the classically confined nodejs snap cannot be used to run a simple mocha test suite for our backend app, as it causes every test to time out. native install, no problem. The classically confined golang snap, installs a bunch of go tools as you'd expect, which are weirdly invisible to VSCode's Golang addons. You install Slack, click a link in a conversation, and it opens in a new Firefox window with all of your settings and addons disappeared; you have to delete an about:profiles profile in Firefox to make it use the existing configuration. App startup times can range from hundreds of milliseconds to 10+ seconds. Its just really not a good situation; some of these problems have solutions, but these are issues I've seen in, who knows, 19.04, 19.10, 20.04, 20.10, 21.04, we'll see if they fix it in 21.10 but I'm not holding my breath; we're talking years of decay. Flatpak is definitely better. I've never ran into any compatibility or functionality issues. But, availability isn't as good; it seems like flatpak is geared more toward UI software; so, Discord, Slack, Spotify, Atom, Steam, even nvidia drivers, these I have installed through flatpak (Manjaro Gnome; so, Arch). You search flathub for Golang, or NodeJS, or other more dev/cli focused software, and it has nothing. So, I don't know if that's a cultural or technical thing, but it at least seems like flatpak has a focus, and excels within that focus.
