Snaps still don't seem to have network storage permissions when I tried ubuntu a week ago, so they suck for me. I put just about everything on my NFS.

A lot of the flatpaks for programs I actually use are third party and not maintained by the actual developer, have missing or enweirdened features because of the sandboxing, and are a removed to run from command line. So I try to avoid those too.

Flatpak made my life much easier. It solves so many problems that the Linux ecosystem had. "Package once, use everywhere" is great.

Snap could have been similarly good, but I think Canonical made some mistakes.

I don't hate Snap. I think a bit of friendly competition is good for both Snap and Flatpak.
