What will you mostly use it for?
The Yunzii B98 Pro wins in scenarios demanding high customization, such as programming, modding, and content creation, thanks to its QMK/VIA firmware and OLED screen. It also holds an edge for gaming due to its specified polling rate. The AULA F99 Pro is better suited for office environments and travel, where its lighter weight is a practical advantage. For general typing, the choice hinges on preference for the AULA's described multi-layer foam sound profile versus the Yunzii's aluminum plate and PBT keycap feel.
Pick the Yunzii B98 PRO
- The Yunzii B98 Pro lists a 1000 Hz polling rate, which the AULA's specifications do not mention.
- Both have N-Key Rollover, but the Yunzii's listed NKRO is explicitly confirmed in its vendor description.
- The Yunzii's aluminum plate may provide a more consistent, rigid platform for rapid key presses.
