Get the Ajazz AK820 Pro if its TFT screen, aluminum case option, polycarbonate plate and lower listed weight suit your priorities. Get the AULA AU75 if its five sound-deadening layers, up-to-five-device switching and LEOBOG Star Vector switch specifications are more useful to you.

What will you mostly use it for?
The AU75 gets the edge for gaming and office use on the basis of its mode-switching knob and vendor-described multi-device switching. The Ajazz takes programming and content creation for buyers who value its display, and it is the lighter, smaller-listed option for travel. For modding, the Ajazz has the more clearly specified plate and PCB construction. Both remain 75% gasket-mount boards with hot-swappable switches, so the categories turn on their distinct extras rather than their shared basics.
Pick the AULA AU75
- The AULA vendor describes its knob as switching between office and gaming modes with a long press.
- Its LEOBOG Star Vector linear switches have a stated actuation force of 40±3gf.
