Pros and Trade-offs

Your primary need dictates the choice. If you require wireless operation, a compact form factor, and a gasket-mounted typing feel, the AULA F99 is the clear candidate. If your priority is maximum performance customization through QMK/VIA, a high polling rate for gaming, and you prefer a traditional full-size layout with adjustable feet, the Keychron C2 Pro is the better tool. Consider your desk setup and software needs carefully.
