Ring pulls it off better, in my opinion. Installation is dead simple, the app works fairly well, and the product is well-designed, all the way down to the packaging/install kit.
I've tried a few other similar products and just haven't been nearly as satisfied with the experiences (mostly due to software quirks).
Ring, like Nest, was simple enough that my technically inept parents managed to deploy and use it without my intervention. That says a lot.
