Aeotec Z-Stick 10 Pro vs Smlight SLZB-07 MG24

It depends on which radios you need. The Smlight SLZB-07 MG24 is the better buy for a pure Zigbee and Thread setup, costing less while adding Zigbee router and Thread border router support. The Aeotec Z-Stick 10 Pro is the one to choose if you also want Z-Wave, since it is the only one of the pair with a Z-Wave controller built in, and it carries the higher owner rating.

Protocol coverage splits them apart. The Z-Stick 10 Pro combines a Z-Wave 800 controller with a Zigbee 3.0 coordinator, giving you both networks from one stick. The SLZB-07 MG24 skips Z-Wave entirely but adds two things the Aeotec lacks: the ability to act as a Zigbee router (extending an existing mesh) and a Thread border router for Matter devices.

The Aeotec Z-Stick 10 Pro, since it is the only one here with a Z-Wave controller, letting you run Z-Wave JS and a Zigbee integration like Zigbee2MQTT from a single USB port instead of buying two separate dongles.

The Smlight SLZB-07 MG24. It costs less than the Z-Stick 10 Pro and, on top of Zigbee coordination, supports Thread border router duties and Zigbee routing, features the Aeotec stick does not include at all since it has no Thread support.

Anyone running Home Assistant who wants to consolidate Z-Wave and Zigbee onto a single USB adapter, and who values the stronger owner rating, should choose the Z-Stick 10 Pro over a Zigbee-only stick.

Buyers who only need Zigbee (with the option to add Thread devices later) and want to spend less should pick the SLZB-07 MG24, especially if they also want the flexibility of using it as a Zigbee router to extend an existing mesh.
