Snaps solve the problems caused by users installing from third party apt repositories. Users do that today. Comparing against the virtues of distribution-provided packages is a strawman.
The exception is distribution packages like Chromium and Firefox. These don't work well in deb format, because users expect the latest upstream updates after the distribution releases, but upstreams add dependencies creating dependency hell for packagers. Snaps work better for this case.
