What will you mostly use it for?
The Ajazz AK820 Pro is the more versatile choice, winning in most categories due to its feature set and lighter design. It is particularly strong for office use, programming, and travel because of its screen, explicit OS support, and lower weight. For gaming, its specified polling rate and N-Key Rollover give it an edge. The two keyboards tie for content creation, as both provide a useful control knob. The Redragon K673 Pro's heavier build did not provide a decisive advantage in any specific use case over the Ajazz's features.
