What will you mostly use it for?
The Lemokey P3 HE dominates pure gaming due to its magnetic switches and advanced features like Rapid Trigger and adjustable actuation. The V3 Ultra is the better travel companion thanks to its light weight and extended battery life, while also being the top choice for modders because of its standard MX switch compatibility and multiple foam layers. In office work, the V3 Ultra's lighter chassis and layout variety give it an edge. Programming and content creation are ties since both keyboards share QMK/VIA support, a knob, and strong typing fundamentals.

Keychron V3 Ultra vs Lemokey P3 HE: your questions
The Keychron V3 Ultra supports an 8000 Hz polling rate in both wired and 2.4 GHz wireless modes, which is eight times higher than the Lemokey P3 HE's 1000 Hz polling rate. This makes the V3 Ultra better suited for users who want the lowest possible input lag in competitive scenarios.
No, the P3 HE is designed exclusively for Gateron double-rail magnetic switches and does not support standard MX-style mechanical switches. The keyboard's hot-swappable PCB is only compatible with magnetic switches sold on the Keychron and Lemokey websites.
The Lemokey P3 HE weighs 1910g compared to the V3 Ultra's 960g, nearly double the weight. The heavier aluminum body of the P3 HE provides more stability during aggressive gaming and reduces vibrations, but it makes the keyboard much less portable for travel.
Both keyboards are programmable through their respective web launchers, but they use different firmware. The V3 Ultra uses ZMK firmware with the Keychron Launcher, while the P3 HE runs QMK firmware and accesses the Lemokey Launcher. Both allow full key remapping, macro creation, and RGB customization.
The Keychron V3 Ultra offers up to 660 hours of battery life with the backlight off, while the Lemokey P3 HE provides up to 120 hours under the same conditions. The V3 Ultra's significantly longer battery life makes it better for users who want to charge less frequently.
The V3 Ultra uses an ABS plastic case and a polycarbonate plate, making it lighter and more flexible, while the P3 HE features a full 6063 aluminum case and aluminum plate for a rigid, premium feel. The P3 HE also includes a mirror-polished finish on the back for aesthetic appeal.
Yes, both the Keychron V3 Ultra and Lemokey P3 HE are hot-swappable, but they accept different types of switches. The V3 Ultra works with nearly all 3-pin and 5-pin MX mechanical switches, while the P3 HE is limited to Gateron double-rail magnetic switches exclusively.
Both keyboards use gasket mount designs and multiple layers of acoustic foam for a refined typing sound. The V3 Ultra with its polycarbonate plate and Silk POM switches offers a softer, quieter typing feel, while the P3 HE's aluminum plate and magnetic switches provide a more solid, stable response.
Yes, both keyboards include a system toggle switch and an additional set of keycaps for both macOS and Windows. They also support Linux and can save two different layouts, one for each operating system, for seamless switching.
The V3 Ultra features south-facing RGB LEDs, while the P3 HE uses north-facing RGB LEDs. Both support per-key RGB and Mix RGB lighting zones with over 22 preset effects, configurable through their respective web-based launchers.
