What will you mostly use it for?
The Keychron V1 Max is the clear choice for programmers and office users who need firmware flexibility or specific international layouts. The Yunzii B75 Pro has an edge for gaming due to its higher advertised polling rate. For modders, the V1 Max's open-source support and barebones availability are significant advantages. Travel and content creation needs are served equally well by both, with minor trade-offs in weight and identical core multimedia features.

Keychron V1 Max vs Yunzii B75 Pro: your questions
The Keychron V1 Max supports QMK and VIA, which are open-source firmware platforms allowing for deep key remapping, macro creation, and layer programming. The Yunzii B75 Pro's vendor description mentions programmable software for Windows, but does not specify support for QMK or VIA.
The Yunzii B75 Pro is listed as compatible with macOS. However, the Keychron V1 Max includes an additional set of keycaps specifically for Mac, a system toggle switch, and is described as being built with Mac users in mind, offering more tailored support.
Yes, both the Keychron V1 Max and Yunzii B75 Pro feature hot-swappable sockets. The V1 Max's product page confirms compatibility with 3-pin and 5-pin MX mechanical switches. The B75 Pro's description also states it is compatible with 3-pin or 5-pin switches.
The Keychron V1 Max is more geared towards modders. It is sold as a barebones kit, supports open-source QMK firmware, uses screw-in stabilizers that support third-party replacements, and has a documented polycarbonate plate and gasket mount design for modifications.
A 4000 Hz polling rate, like that advertised for the Yunzii B75 Pro, can offer lower input latency than a 1000 Hz rate in theory, which may benefit competitive gaming. The Keychron V1 Max has a 1000 Hz rate, which is still considered excellent for most users and games.
Yes. The Keychron V1 Max comes with OSA profile double-shot PBT keycaps, which have an OEM height and SA-like shape. The Yunzii B75 Pro comes with double-shot PBT keycaps in a Cherry profile. Both use non-shine-through legends with south-facing RGB.
Both keyboards have the same 4000mAh battery capacity. The Keychron vendor page provides specific lab test estimates for battery life with RGB on and off, while the Yunzii description states it delivers extended usage times but does not give specific hour estimates.
Yes. The Keychron V1 Max explicitly supports an ISO-DE (German) layout, among many other specific regional ISO layouts like UK, Nordic, Spanish, and French. The Yunzii B75 Pro lists support for ISO but does not specify these regional variants.
Yes, both the Keychron V1 Max and the Yunzii B75 Pro include a multi-function control knob. The vendor descriptions indicate the knob can be used for volume control and adjusting RGB lighting effects.
The Yunzii B75 Pro is heavier, with a listed weight of 937g. The Keychron V1 Max weighs 770g. The difference of 167g may be a factor for portability.
The product listings do not specify console compatibility for either keyboard. They are confirmed to be compatible with Windows, macOS, and Linux systems via wired and wireless connections.
