What will you mostly use it for?
The RK84 has the edge for gaming, office use, programming, travel, and content creation based on its listed polling rate, pass-through ports, media keys, and specified battery. The YZ84 is the more modding-oriented pick, with explicitly described 3-pin and 5-pin switch replacement and a DIY kit/barebones listing. These differences matter more than the shared 75% layout and tri-mode connectivity. For either keyboard, switch selection and your preference for the listed features should guide the final choice.
