Compare AULA HERO84 HE vs Keychron K2 HE Differences Side by Side

This comparison is for buyers deciding between two 75% magnetic switch keyboards with different core philosophies. The AULA HERO84 HE is a wired-only, performance-focused board with an 8000 Hz polling rate, while the Keychron K2 HE offers tri-mode wireless connectivity and deep customization via QMK/VIA. The decision is difficult because both feature hall effect switches with rapid trigger and adjustable actuation, but prioritize different aspects of the user experience.
