I have Zooz, a couple GE, and formerly had Lutron Caseta. I like my Zooz switches the best. They have a ton of functionality that other switches don't offer (except innovelli. Zooz and Innovelli functionalities are very similar). I'd recommend them over anything else if you have neutral wires in your boxes. If not, I'd buy Innovelli. My primary reason for recommending Zooz over Innovelli is price. Both have great customer service and a great product, but Zooz are cheaper and offer sales frequently, making them significantly cheaper. As for the Zen30 switch, I don't have experience, but it's a simple on/off switch, so if you want to control a ceiling fan with it, you'll still be using another remote or the pull string to change speeds/fan direction.
