What will you mostly use it for?
The Q3 Ultra is the stronger choice for gaming and travel due to its 8K polling and lighter, more compact frame. For office work and content creation, the Q5 Max's full-size 96% layout with a numpad is the clear winner. Both are excellent for programming and offer similar sound dampening, but the Q5 Max edges ahead for modders thanks to its QMK firmware. The Q3 Ultra's exceptional battery life and lower weight make it the more portable option.
Pick the Keychron Q3 Ultra
- The Q3 Ultra features an 8000 Hz polling rate in both wired and 2.4 GHz modes, compared to the Q5 Max's 1000 Hz.
- The Q3 Ultra's 80% TKL layout provides more space for mouse movement.

“I don't like writing reviews but I do like reading them lol. What I am trying to say is that don't sleep in this keyboard. I even liked it more than my Lemokey L3. I got the one with the side printed keys and banana switches. This is my 3rd keychron keyboard.”

“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.”

Keychron Q5 Max vs Q3 Ultra: your questions
The Keychron Q3 Ultra has the better polling rate for gaming, offering 8000 Hz in both wired and 2.4 GHz modes. The Keychron Q5 Max has a 1000 Hz polling rate, which is still very capable for most gamers but not as fast as the Q3 Ultra.
Only the Keychron Q5 Max has a full numpad, as it uses a 96% layout. The Keychron Q3 Ultra is an 80% TKL layout and does not include a numpad, which can be a deciding factor for users who frequently enter numbers.
The Keychron Q3 Ultra has the superior battery life, offering up to 660 hours of use with the backlight off. The Keychron Q5 Max is rated for up to 180 hours with the backlight off. The Q3 Ultra also lasts up to 200 hours with RGB on, while the Q5 Max lasts up to 100 hours at the lowest brightness.
The Keychron Q3 Ultra is easier to carry due to its smaller TKL size and lighter weight of around 1787 grams. The Keychron Q5 Max is larger and heavier at 2215 grams, making it more suited for a stationary desk setup.

Yes, both the Keychron Q5 Max and Q3 Ultra support macOS and Windows out of the box. Each comes with a system toggle switch and an additional set of customized keycaps for both operating systems. Linux compatibility is also mentioned for the Q5 Max.
Both keyboards feature a full CNC aluminum body with a double-gasket design, so build quality is high on either side. The Q5 Max has a slightly higher internal build quality score, but the Q3 Ultra is noted for its sturdy, tank-like construction in user reviews.
Both are excellent for programming, offering comfortable typing from their gasket mount designs and full key remapping. The choice comes down to layout preference: the Q5 Max provides a numpad for code comments and data, while the Q3 Ultra saves desk space for a more minimalist setup.
