What will you mostly use it for?
For gaming, the Q3 Ultra wins with its 8000 Hz polling rate for the lowest latency. For programming, modding, and content creation, the L3 takes the lead thanks to QMK/VIA support, a dedicated macro column, and a barebones option. Office and travel result in ties, as both keyboards share similar build quality, battery life, and portability constraints.
Pick the Keychron Q3 Ultra
- 8000 Hz polling rate in both wired and 2.4 GHz wireless modes offers lower input lag.
- Designed with a high-performance chip (MCU) with 1MB flash for competitive gaming.

“USB is working for me, but I have it plugged in to a USB switcher. I haven't configured the keyboard, beyond the switches in the back. I'm liking the keyboard so far.”
“USB on keeps dropping out, even after firmware update (1.0.2) and reset. Tried multiple computers, windows and Mac. Half the time it doesn’t work at all.”

“The Lemokey L3 is a piece of industrial art. Solid build quality. Awesome typing experience. This could very well be the last keyboard I'll buy.”

Keychron Q3 Ultra vs Lemokey L3: your questions
The Keychron Q3 Ultra offers an 8000 Hz polling rate in both wired and 2.4 GHz wireless modes. The Lemokey L3 has a 1000 Hz polling rate in wired and 2.4 GHz modes, which is lower than the Q3 Ultra.
Yes, the Lemokey L3 uses the open-sourced QMK firmware and is compatible with VIA software for remapping keys and creating macros. Users need to download a JSON file and import it into VIA for the L3 keymap to work.
Yes, the Q3 Ultra comes with a system toggle and an additional set of keycaps for both macOS and Windows. It allows you to save two different layouts, one for each system.
The Lemokey L3 comes with Cherry profile double-shot PBT keycaps. These are non-backlight shine-through, meaning they are durable and oil-resistant but do not show RGB lighting through the legends.
No, the Keychron Q3 Ultra does not feature a dedicated macro column. It has a knob but relies on its ZMK firmware and Launcher web app for key remapping and macro creation instead.
According to the manufacturer, the Q3 Ultra's 4000 mAh battery lasts up to 660 hours with the backlight turned off. With RGB at lowest brightness, battery life is rated up to 200 hours.
Yes, the Lemokey L3 is sold in both a Fully Assembled version and a Barebone Knob version. The barebones option does not include keycaps or switches, allowing you to choose your own.
Yes, both the Keychron Q3 Ultra and the Lemokey L3 use screw-in PCB stabilizers. These are designed to provide a more stable and less wobbly typing experience on larger keys like the space bar and shift.
The Lemokey L3 is heavier at about 1976 grams for the fully assembled version. The Keychron Q3 Ultra weighs approximately 1787 grams, making the L3 the bulkier option.
The Q3 Ultra uses Keychron's spherical-angle (KSA profile) double-shot PBT keycaps. These are also non-backlight shine-through, meaning they are oil-resistant but do not show legends when backlit.
Yes, both the Keychron Q3 Ultra and the Lemokey L3 feature hot-swappable PCBs. They support almost all 3-pin and 5-pin MX style mechanical switches, including Cherry, Gateron, and Kailh, without soldering.
The Lemokey L3 is better for macro programming due to its QMK/VIA support and dedicated macro column (M1, M2, M3 keys). The Q3 Ultra uses ZMK firmware and a Launcher web app but lacks dedicated macro keys.
