It adds a camera, motion and ambient light sensing, and a built-in Zigbee coordinator and Thread border router, none of which the Google Nest Mini (2nd gen) has, and it rates higher with owners too. The Nest Mini answers with the lower price of the two and a shape built to disappear flush against a wall, adding Google Assistant to a room for very little money. Choose the Amazon Echo Show 21 if you want a TV-sized Alexa display that anchors the smart home, and the Google Nest Mini (2nd gen) if you just want cheap Google voice control in extra rooms.

What the differences mean

Screen and hub hardware

The Amazon Echo Show 21 is built around a 21-inch touchscreen with a camera, motion and ambient light sensors, and its own Zigbee coordinator and Thread border router; the Google Nest Mini (2nd gen) has none of that, only a Matter bridge.

Ecosystem

The Amazon Echo Show 21 runs Alexa and the Google Nest Mini (2nd gen) runs Google Assistant; picking between them mostly comes down to which platform the rest of the home already uses.

Price and size

The Google Nest Mini (2nd gen) is a fraction of the size and the price of the Amazon Echo Show 21, built to add basic voice control to a room rather than to anchor the smart home.

Wall mounting

Both mount flush to a wall, but for very different jobs: the Google Nest Mini (2nd gen) disappears into a hallway or bedroom, while the Amazon Echo Show 21 hangs like a screen meant to be looked at.

Which one to buy if

What owners say

Owners of the Amazon Echo Show 21 describe mounting it in the kitchen in place of a small television, using the built-in Fire TV to stream while cooking and running the family calendar from the same screen, and several specifically credit its Zigbee, Thread and Matter hub for finally centralizing a house full of devices. Their main complaint is that the speakers do not match the size of the screen, with volume and bass some call underwhelming. Google Nest Mini (2nd gen) owners instead praise how much bigger it sounds than its tiny size suggests and use it as a wall-mounted chime speaker to make a Nest video doorbell audible indoors, though a handful report it defaulting to the wrong language out of the box or occasionally mishearing a command.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
