The 21 inch display, 6 GHz Wi-Fi, Zigbee and Thread, and motion plus ambient-light sensors are the lead.

What the differences mean

Display against speaker

The Amazon Echo Show 21 is a 21 inch 1920 x 1080 touchscreen, 540 x 350 x 38 mm, with a wall mount, a camera and an off switch. The Google Nest Audio has no screen and no camera and weighs 1200 g. One replaces a small TV. The other fills a room with sound and nothing to look at.

Assistant and local talk

The Amazon Echo Show 21 speaks Alexa, not Google Home, and its conversation stays in the cloud. The Google Nest Audio speaks Google Home, not Alexa, and its conversation agent can run on the device as well as in the cloud. Speech-to-text is cloud-only on both. Neither supports Apple Home or SmartThings.

Radios

The Amazon Echo Show 21 has 6 GHz Wi-Fi, a Zigbee coordinator, a Thread border router and a Matter bridge, and no Ethernet. The Google Nest Audio is dual-band only, with a Matter bridge and no Zigbee, no Thread and no 6 GHz. The connectivity win is that extra Wi-Fi band plus the hub radios, not a network port.

Sensors

The Amazon Echo Show 21 has motion and ambient light, and no temperature or humidity sensor. The Google Nest Audio has none of those four. A routine that starts when someone walks past the display has a sensor on the Show and nowhere to look on the speaker.

What owners say

Owners are not comparing two speakers. Amazon Echo Show 21 owners talk about a sharp 21 inch picture you can read across the room, Fire TV as a kitchen television, and a wall place for calendars and reminders. They say the speakers feel small for that picture, calendars outside Alexa sync poorly, and the Alexa+ rollout had rough edges. Google Nest Audio owners lead with sound that steps up from a smaller Nest speaker, easy Google Home setup, and stereo pairing. They mention Bluetooth disconnects, trouble requesting a specific song, and the obvious lack of a screen.

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.
