Full Voice Assistants comparison in 2026

Updated October 2026
Data from Amazon.
2026 verdict
Control panel or family TV? The Amazon Echo Show 21 takes it over the Amazon Echo Hub, with a 21-inch Full HD screen, a camera and the glass-break and smoke alarm alerts the panel does not offer.

It also adds Wi-Fi 6E and is the better reviewed of the two. The Amazon Echo Hub is a slim 8-inch panel built only to run the smart home: it adds Ethernet and an ambient light sensor and costs noticeably less. Both hang on a wall and are Zigbee coordinators, Thread border routers and Matter bridges with a motion sensor and a one year warranty. Pick the Amazon Echo Hub as a dedicated control panel, and the Amazon Echo Show 21 if the screen should also stream TV and make video calls.

What the differences mean

Purpose

The Amazon Echo Hub is a smart home control panel with no camera and no media focus; the Amazon Echo Show 21 is a full smart display that streams TV and makes video calls.

Screen

8 inches at 1280 x 800 on the Amazon Echo Hub against 21 inches at 1920 x 1080 on the Amazon Echo Show 21. The panel is for tapping at arm's length, the Show for watching.

Wired network

The Amazon Echo Hub has an Ethernet port, useful for a panel that runs the house; the Amazon Echo Show 21 is Wi-Fi only, with 6 GHz support.

Sound alerts

The Amazon Echo Show 21 can listen for glass breaking and smoke or CO alarms with a subscription; the Amazon Echo Hub offers neither.

Size

The Amazon Echo Hub is 15 mm thin and weighs 365 g; the Amazon Echo Show 21 weighs about 4.8 kg and takes a large area of wall.

What owners say

Owners of both like how quickly they set up and that each can run Zigbee, Thread and Matter devices directly. Amazon Echo Hub owners who use it as a dedicated automation panel are glad they bought it, praising a clean touchscreen and one place for cameras, locks and lights; others say the software feels slow or unfinished and that it is no Echo Show substitute for media or calls. Amazon Echo Show 21 owners praise a screen readable from across the room and built-in Fire TV that makes it a real TV; they find the speakers weak for its size, non-Alexa calendar syncing limited and the Alexa+ rollout rough.
