What will you mostly use it for?
The YZ84 Pro has the edge for office typing, programming, and switch experimentation, with its gasket mount, foam layers, PBT keycaps, and support for 3-pin or 5-pin switches. It is also the stronger travel pick on listed battery capacity, though its weight is not specified. Gaming is a close call because both have tri-mode wireless connectivity, hot-swap support, and RGB, while only the RK84’s polling rate is documented. For a desk with peripherals or media controls in regular use, the RK84’s pass-through ports and multimedia keys are the clearer differentiators.
It's a tie
- Both keyboards offer Bluetooth, 2.4 GHz, and wired connectivity.
- Both are 75% layouts with hot-swappable switches and RGB lighting.
- The RK84 lists a 1000 Hz polling rate; no polling-rate figure is specified for the YZ84 Pro.
