Keychron K3 vs Keychron K7

The Keychron K3 and the Keychron K7 are very similar wireless keyboards, but the K3 has more keys. The K3 is a 75% board with a dedicated F-row and a Control button on its right side, which the K7 lacks because of its second Fn key. On the other hand, the K7 is a 65% board with two incline settings, unlike the K3. Both boards are available with Gateron Low Profile and Keychron Low Profile Optical switches. The K3's hot-swappable variant is compatible with Keychron Low Profile Optical switches only, while the K7 is also available with Gateron Low Profile switches.
