Should I buy the NuPhy Air75 or Keychron K3 Pro?

Choosing between the NuPhy Air75 and the Keychron K3 Pro mostly comes down to how you’ll use it.

• Buy the NuPhy Air75 if you care more about gaming or lower-latency feel. It’s often the better pick if you want a faster-feeling experience and a keyboard that can also be customized with macros.
• Buy the Keychron K3 Pro if you want a more work-focused board. It’s a strong choice for office use, and its QMK/VIA support makes key remapping flexible across macOS, Windows, and Linux.

If you want the short version: NuPhy Air75 for gaming; Keychron K3 Pro for productivity and customization.

If you’re comparing newer revisions, it’s worth checking the exact version before buying, since newer models can have different polling rates or build changes.
