“very compact, build quality is great, and I don't even feel any latency when using the keyboard wireless.”
“The only "zmk" support is from the launcher itself and its missing most of the ZMK features. For example Combos!”

Keychron K2 Max vs K2 Ultra: your questions
The K2 Ultra supports an 8000 Hz polling rate in both 2.4 GHz wireless and wired modes, as stated in the vendor description. The K2 Max is limited to a 1000 Hz polling rate. This makes the K2 Ultra more suitable for gamers seeking lower input latency.
Yes, both keyboards include keycaps for Windows and macOS and feature a system toggle to switch between the two operating systems. According to the vendor pages, each comes with an additional set of keycaps to accommodate both platforms.
Yes, both models are hot-swappable and are compatible with almost all 3-pin and 5-pin MX-style mechanical switches, including Cherry, Gateron, and Kailh. This allows users to change switches without soldering, as confirmed in the product descriptions.
Both keyboards feature double-shot PBT keycaps. The K2 Max comes with OSA profile (OEM profile with spherical-angle) keycaps, while the K2 Ultra uses OSA double-shot PBT keycaps. Both are described as oil-resistant and durable.
The K2 Max is lighter at 940 grams, while the K2 Ultra weighs 1084 grams. The K2 Max's lower weight and compact dimensions (32 x 317 x 122 mm) make it the more portable choice for travel, though both share a similar 75% footprint.
The K2 Max uses QMK open-source firmware and also supports VIA for customization via the Keychron Launcher web app. The K2 Ultra runs on ZMK firmware and is also programmable through the Keychron Launcher web app, according to the respective vendor descriptions.
Yes, the K2 Ultra includes knob support as listed in its extra features, making it convenient for adjusting volume or other functions. The K2 Max does not have a knob. This can be a deciding factor for users who prefer physical controls.
Both keyboards are equipped with a 4000 mAh rechargeable lithium polymer battery. According to the vendor pages, the K2 Max offers up to 190 hours of usage, while the K2 Ultra can achieve up to 760 hours at an 8K polling rate with backlight off.
Both models feature screw-in PCB stabilizers. The K2 Max's product page specifically mentions upgraded stabilizers with reinforced sidewalls for improved stability on large keys. The K2 Ultra also uses screw-in PCB stabilizers as stated in its specs.
The K2 Ultra is better for competitive gaming due to its 8000 Hz polling rate in wireless and wired modes, which provides lower latency. The K2 Max's 1000 Hz polling rate is still capable but less responsive. The K2 Ultra's pre-lubed Apex switches also offer enhanced stability.
