I've written this comment several times, but it basically spams your system folders, mounts, daemons, and more. Integration is clumsy and poor. It doesn't give much ability to configure it either. Canonical just doesn't have the human-enginering chops/resources to polish all the rough edges. Sorta reminds me of docker, good ideas, middle-brow execution.
Add in poor startup performance, and I removed it. Replaced Chromium snap with a PPA, which was faster and 10x less intrusive.
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.
Just gave Snap another try last night and I was astonished at the slowness (both for package installation and program startup times)
can't really think of a single thing about the experience that I liked, and it even seemed bad compared to other container systems, like Docker and Flatpak
