The 21 inch Full HD display, 6 GHz Wi-Fi, a one-year warranty and Zigbee plus Thread hub radios are why it wins, even though the Amazon Echo Dot (5th Gen) is the more affordable and the better reviewed. That Dot is a 304 g speaker with no screen, a motion sensor and a temperature sensor, and only a Matter bridge for local radios. Both speak Alexa only, with partial Home Assistant support and no Apple Home or SmartThings. Buy the Amazon Echo Show 21 to hang a family display on the wall, and the Amazon Echo Dot (5th Gen) to drop a voice assistant into a bedroom.

What the differences mean

A screen, or none

The Amazon Echo Show 21 is a 21 inch 1920 x 1080 color touchscreen you can wall-mount and use as a Fire TV. The Amazon Echo Dot (5th Gen) has no screen at all, so timers, lyrics and camera feeds stay in another device. That is the whole reason these two are not substitutes.

Hub radios

The Amazon Echo Show 21 is a Zigbee coordinator, a Thread border router and a Matter bridge. The Amazon Echo Dot (5th Gen) has the Matter bridge only, with no Zigbee coordinator and no Thread border router. A house of Zigbee sensors still needs another hub if the Dot is the only voice assistant.

Wi-Fi and warranty

The Amazon Echo Show 21 adds 6 GHz Wi-Fi and a 1 year warranty. The Amazon Echo Dot (5th Gen) is dual-band only, with no 6 GHz and no Ethernet, and the warranty is 90 days. Both have Bluetooth and a microphone off switch.

Sensors

The Amazon Echo Dot (5th Gen) has a motion sensor and a temperature sensor, and no ambient-light sensor. The Amazon Echo Show 21 has motion and ambient light, and no temperature or humidity sensor. Neither gives you the full set, so the useful one depends on whether you want room temperature or a screen that reacts to light.

What owners say

Owners agree that setup is quick, then they want opposite things from the box. Amazon Echo Dot (5th Gen) owners talk about sound that is fuller than a speaker this small suggests, a microphone switch, and Voice Match, and they note there is nothing to look at, a 90-day warranty, and a status light that is hard to see unless the unit is at eye level. Amazon Echo Show 21 owners talk about a sharp 21 inch picture, Fire TV as a real second television, and a wall-mounted place for calendars. They complain that the speakers feel small for that picture, that calendars outside Alexa sync poorly, and that the Alexa+ rollout had rough edges.

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.
