What will you mostly use it for?
The Yunzii B75 Pro wins in most categories due to its feature-rich design, including a control knob, gasket mount, and PBT keycaps. It is the stronger choice for gaming, office work, programming, and content creation where these features add tangible value. The RK84 Pro's primary advantage is its substantial aluminum build, which may appeal to users prioritizing a rigid, premium-feeling case, especially for travel where its weight adds stability.

Royal Kludge RK84 Pro vs Yunzii B75 Pro: your questions
Both keyboards support Bluetooth, 2.4 GHz, and wired USB-C connections. However, the Royal Kludge vendor page includes customer reviews specifically citing poor wireless connectivity performance for the RK84 Pro. The Yunzii B75 Pro's listing does not mention similar issues.
Yes, both the Royal Kludge RK84 Pro and the Yunzii B75 Pro feature hot-swappable PCBs. This allows you to change the mechanical switches without soldering. The RK84 Pro's vendor page confirms compatibility with 3-pin and 5-pin switches.
The typing feel differs primarily due to the mounting style. The Yunzii B75 Pro uses a gasket mount design with sound dampening, which typically offers a softer, more flexible typing experience. The RK84 Pro uses a standard mount within a rigid aluminum case, likely resulting in a firmer, more direct feel.
The Yunzii B75 Pro has a slightly larger 4000mAh battery compared to the RK84 Pro's 3750mAh battery. In practice, battery life will vary significantly based on RGB usage and connection mode, but the B75 Pro has a marginal capacity advantage.
Yes, both the Royal Kludge RK84 Pro and the Yunzii B75 Pro list Mac support in their specifications. The RK84 Pro's vendor description explicitly states compatibility with MacOS.
The Yunzii B75 Pro is likely better suited for shared spaces. It features built-in sound dampening and uses pre-lubricated switches according to its description, which can reduce noise. Its PBT keycaps also produce a slightly deeper sound than ABS.

Only the Yunzii B75 Pro specifies that it has south-facing RGB LEDs. South-facing LEDs prevent interference with Cherry-profile keycaps and can provide a more consistent glow. The RK84 Pro's RGB orientation is not specified.
The Royal Kludge RK84 Pro is notably heavier at 1290 grams (about 2.84 lbs) compared to the Yunzii B75 Pro's 937 grams (about 2.07 lbs). This extra weight, largely due to its aluminum case, can make the RK84 Pro feel more stable and planted on a desk.
Yes, both keyboards support programmability. The RK84 Pro mentions DIY software support, and the Yunzii B75 Pro description states its programmable software allows for redefining keys and setting macros in Windows.
