Our Verdict

Ducky OK-M

Keychron J2 [J4, J5, etc.]

The Ducky OK-M series and the Keychron J series are lineups of wireless mechanical keyboards available in several sizes. They offer similarly excellent typing experiences and the same flexible wireless connectivity. The Ducky keyboards are available in 75%, 65%, and 98% sizes, while the Keychron boards are available in 75%, 80%, and full-size models. The Keychron boards also have better build quality, better gaming performance, and some colorway options have shine-through keycaps, which the Ducky boards lack.
