What will you mostly use it for?
The Keychron K3 Pro wins in most scenarios that benefit from its modern features, particularly for office use, programming, travel, and modding due to its wireless connectivity, programmability, and hot-swappable design. The Ducky One 2 SF's advantages are more niche, tied to its specific 65% form factor and included PBT keycaps. For gaming and content creation, the choice is less clear-cut and depends on whether you value the Ducky's size or the Keychron's flexibility.
It's a tie
- Both keyboards offer a 1000Hz polling rate for responsive input.
- The Ducky One 2 SF has a slightly more compact 65% layout for more mouse space.
- The Keychron K3 Pro's wired mode provides the same low-latency performance.
