What will you mostly use it for?
The Keychron takes most of these categories on the strength of its QMK/VIA support, knob, and layout options. The AL75 is a plausible travel alternative for buyers who value its larger battery, but its substantially higher listed weight is a trade-off. Both offer wireless and wired connectivity, hot-swap capability, and a 1000 Hz polling rate. The AL75's aluminum case is its clearest material distinction from the Keychron's ABS housing.
Pick the Keychron V1 Max
- Both list a 1000 Hz polling rate, while the Keychron specifies that rate for 2.4 GHz and wired use.
- The Keychron adds QMK/VIA support and N-key rollover in wired and wireless modes.
- The AL75's vendor description specifies 1000 Hz polling for USB-C wired mode.
