Well yes: if Canonical cared they could make most of their snaps work almost as good as the Debian packages they dropped, and then it would be the same to the user.

But also no: even if they spent years catching up they would not reach the level of not-sucking that .deb get without extra effort, as a result of decades of policy ossified into the supporting tools. Such as the strong expectation that apt deals with packages that can be (re)built from their declared inputs and share common build-essentials. Whereas snapcraft does not even provide the tools yet to easily rule out building from ephemeral inputs or merely-accidentally working rust versions.
