The Amazon Echo Show and Google Nest Hub each house a digital assistant: Alexa and Google Assistant. These assistants have their strengths and weaknesses. Alexa, for instance, works with a wider variety of devices and sports more features, whereas Google responds more intuitively to commands. Despite a pretty even split here, though, the Google Nest Hub boasts enough distinctive features to make it our recommendation for a smart display.
First, Google's display manages a large number of smart home gadgets more elegantly, organizing them into an easy-to-understand control panel for touch controls. Organization goes a long way, it seems, as the cooking assistance offered by the Nest Hub (step-by-step recipes, simultaneous music and video streaming and so on) gains a slight edge over the Echo Show for its intuitive interface.
Speaking of streaming video, the Echo Show boasts a significantly larger display than Google's (10 versus 7 inches), but it's hard to beat the presence of YouTube (owned by Google) on the Nest Hub. Finally, a few nice design touches, such as how the Nest Hub adapts the brightness and warmth of the photos it displays to match the room, really bring together Google's product as the more aesthetically pleasing device.
Since the two devices are close on most fronts, you should go with the Amazon Echo Show if you prefer Alexa. You should also go with the Echo Show if you want a smart display that sounds good when playing music. However, if you're a Google fan or if you're on the fence, the Google Nest Hub is the better choice.
It costs less, and it's better at controlling your smart home, walking you through recipes and showing your personal pictures. You probably don't need your smart display to be your main screen for watching TV or your main speaker for listening to music. Smart displays are best at showing you what you need to know to keep your hands free in the kitchen. The Google Nest Hub is great at that, and it's the better smart display as a result.
