Our Verdict

Ducky One 2 SF

Keychron K3

The Ducky One 2 SF and the Keychron K3 are quite different. The Ducky is a wired-only 60% keyboard, while the Keychron is a low-profile wireless keyboard with a 75% layout. The Keychron is more versatile because it can be used with a wider variety of devices or even in a home theater PC setup. Also, it has full compatibility with macOS and Android, whereas the Ducky is only fully compatible with Windows. However, the Keychron doesn't have any macro-programmable keys like the Ducky. The two keyboards are available in a wide variety of switch options. Unfortunately, they both have relatively high latency, so neither of them is ideal for fast-paced gaming.
