I have the Cozyla and my wife primarily purchased it because it was no subscription.
It came very well boxed up with quality mounting hardware. Is it better than the Echo Show or Skylight? I’d say it’s better than the Echo because the Amazon products have wasted space where they want to pretend the content isn’t an ad for other interests but it is. The Skylight to me represents the best blend of hardware and software. You can still get functionality without subscribing to their services.
In hindsight I would have probably recommended my wife by the Skylight because the Mobile App looks a lot more functional than the Cozyla.
