I don't think so. I'm on Ubuntu and mostly use debs (apt), I'll use Snaps if that's the easiest way to get an update. I use Appimages for some ephemeral stuff or when that's the only way developers release it (some 3d printing stuff). I haven't installed Flatpaks at all because it doesn't jibe with the distro overall.
