What will you mostly use it for?
The Keychron K2 Pro is the more versatile choice for most structured use cases, winning in Gaming, Office, Programming, and Modding due to its specified performance specs, layout support, firmware, and modding-friendly design. The AULA M75 takes the lead for Travel solely based on its much larger battery capacity and inclusion of a 2.4 GHz dongle. For Content Creation, the decision is a tie, leaning on shared core features like RGB and hot-swap, leaving the choice to personal preference for typing feel versus software control.

AULA M75 vs Keychron K2 Pro: your questions
The AULA M75 has a significantly larger 8000mAh battery, while the Keychron K2 Pro has a 4000mAh battery. Based on capacity alone, the AULA M75 should offer longer usage between charges.
The Keychron K2 Pro supports full key remapping and macro creation through its QMK and VIA firmware support. The AULA M75's vendor description does not mention similar advanced software customization features.
Yes, the Keychron K2 Pro is fully compatible with both Mac and Windows operating systems. Its product listing states it includes keycaps for both systems.
The AULA M75 supports three connectivity modes: Bluetooth, 2.4 GHz wireless with a dongle, and wired USB. The Keychron K2 Pro supports Bluetooth and wired modes, but not a dedicated 2.4 GHz mode.
