What will you mostly use it for?
The Ajazz takes the edge for gaming, office work, travel, and content creation, largely because of its N-key rollover, screen, and lower listed weight. The Redragon is the more compelling pick for programming and modding if its macro software or stated switch socket support fits your plans. Both share a 75% layout, linear switches, wireless and wired modes, and a knob. Consider the Ajazz’s south-facing LED keycap caveat before choosing it.
