What the differences mean

Screen size

21 inches at Full HD against 7 inches at 1024 x 600. The Amazon Echo Show 21 is a wall TV and family board; the Google Nest Hub (2nd Gen) is a bedside or countertop display you read up close.

Camera

The Amazon Echo Show 21 has a camera with a hardware off switch for video calls; the Google Nest Hub (2nd Gen) has none, which suits a bedroom but rules out calls.

Zigbee

Both are Thread border routers and Matter bridges, but only the Amazon Echo Show 21 is a Zigbee coordinator that can pair Zigbee devices without another hub.

Assistant

The Amazon Echo Show 21 runs Alexa only and the Google Nest Hub (2nd Gen) Google Assistant only. Whichever platform your other devices use settles most of this comparison.

Placement

The Amazon Echo Show 21 is built for the wall and weighs about 4.8 kg; the Google Nest Hub (2nd Gen) weighs 558 g and sits on a nightstand or counter.

What owners say

Owners of both displays praise a quick setup and a sharp screen they use for recipes, calendars and photos. Amazon Echo Show 21 owners single out built-in Fire TV, which turns it into a real kitchen television, and a screen readable from across the room; they complain that the speakers feel underwhelming for its size, that syncing a Google or Apple calendar is limited and that the Alexa+ rollout has brought rough edges. Google Nest Hub (2nd Gen) owners use it as a bedside clock with sleep sensing or a small kitchen speaker and say it blends into a Google Home; their complaints are no camera for video calls, voice recognition that feels rigid with natural phrasing and patchy support outside the Google ecosystem.
