What will you mostly use it for?
The K2 Pro leads for buyers who need ISO options, broader keymap customization, or software support across multiple operating systems. The AL75 is the more suitable travel-oriented option on battery capacity and connection choices, though it is the heavier keyboard by listed weight. Gaming is a close call based on the listed polling rate and N-key rollover, with 2.4 GHz as an extra connection option on the Yunzii. Both support switch swapping, but the K2 Pro provides more explicit firmware and stabilizer details.
It's a tie
- Both list a 1000 Hz polling rate and N-key rollover.
- The AL75 explicitly lists a 1000 Hz polling rate for USB-C wired mode, while the K2 Pro lists 1000 Hz without limiting that figure to one connection mode.
- The AL75 adds 2.4 GHz wireless; the K2 Pro offers hot-swappable switches and QMK support.
