It's been a while since I evaluated them all since I'm a Nix user so my portability needs are met already, and it seems like the sandboxing stuff is still getting worked out, but my impression the last time I looked was that Flatpak was better thought out.

The mountpoints thing seems very minor and cosmetic to me, though.

I guess it sucks to be surprised by something that's only kind of okay.
