It’s the worst possible implementation of distro independent binary delivery, highly dependent on a gazillion other things to barely operate, is counterintuitive as soon as you start using it, depends on canonical goodwill (which is always in a state of flux), actually mostly work everywhere but really only work correctly on a very limited subset of distributions, and requires a lot of work to basically achieve nothing more than what already existed OR any of the alternatives that are more lightweight, easier to implement for developers, easier to use of end users.

tl;dr: it’s not great
Basically, if a task calls for snap, use Flatpak
