Data from the official Aqara and Sonoff sites.
2026 verdict
The Aqara Hub M2 is the better pick between these two Zigbee hubs, mainly because it is the lower priced one and adds Bluetooth and an infrared blaster that the Sonoff Zigbee Bridge Ultra lacks.
The Sonoff Zigbee Bridge Ultra is the newer, more powerful box, with a 1.5 GHz dual-core processor, 1 GB of memory, room for 256 subdevices, a two-year warranty and a higher owner rating. Both are Matter bridges with Ethernet, 2.4 GHz Wi-Fi and a built-in speaker, and both work with Apple Home, Google Home, Alexa, SmartThings and Home Assistant. Neither has Z-Wave or Thread. Choose the Aqara Hub M2 for Aqara gear and IR control, and the Sonoff Zigbee Bridge Ultra for a large Sonoff-led network.

What the differences mean
Processing power and capacity
The Sonoff Zigbee Bridge Ultra has a 1.5 GHz dual-core processor, 1 GB of memory, 8 GB of storage and takes up to 256 subdevices. The Aqara Hub M2 does not publish its hardware and takes 128, which is still plenty for most homes.
IR and Bluetooth
The Aqara Hub M2 has an IR blaster for TVs and air conditioners and Bluetooth for setup. The Sonoff Zigbee Bridge Ultra has neither.
Third-party Zigbee devices
The catalog lists third-party device support for the Sonoff Zigbee Bridge Ultra and not for the Aqara Hub M2, which is built for Aqara gear. Owners of the Sonoff still report limits, such as Philips Hue bulbs that will not pair, so check your devices first.
Warranty
The Sonoff Zigbee Bridge Ultra carries a two-year warranty. The Aqara Hub M2 does not publish one in the catalog.
What is the same
Both are Zigbee coordinators and Matter bridges with Ethernet, 2.4 GHz Wi-Fi and a built-in speaker, and neither has Z-Wave, Thread, a microSD slot or a microphone.

What owners say
Owners of both hubs treat them as the reliable core of a Zigbee network, and both groups run into limits on pairing brands they were not designed for. Aqara Hub M2 owners say Aqara sensors that dropped offline on a generic stick became stable, like the IR blaster and years of steady service, and complain about HomeKit showing the hub as a Security System, some units going offline and a Wi-Fi change forcing them to re-pair every child device. Sonoff Zigbee Bridge Ultra owners describe a large step up in stability over the older ZB Bridge-P, easy setup and clean Home Assistant use, and they warn that Philips Hue bulbs will not pair, that Alexa and Google sometimes misread sensor values, that the advertised range is overstated and that a few devices, such as water valves, are not fully supported.
