Amazon Echo Show 21 vs Google Nest Hub (2nd Gen) comparison

Updated June 2026

Data from Amazon and official Google site.

2026 verdict

A giant against a pixie: the Amazon Echo Show 21 wins on rating, hub radios, screen size and camera, its 21-inch Full HD wall presence, Fire TV, shuttered camera and Zigbee coordination overwhelming the 7-inch, camera-free Nest. The Google Nest Hub (2nd Gen) holds the corners the giant cannot reach: a fraction of the price, bedside Sleep Sensing by radar, ambient light awareness and Google Assistant. The ecosystems never overlap, so allegiance often decides first. On capability it is a rout for the Amazon Echo Show 21; on gentle bedroom duty and budget, the Nest Hub survives happily.
