Keychron K4 HE vs ASUS ROG Falchion Ace 75 HE

The Keychron K4 HE is the better pick for most people deciding between these two. It gives you a full number pad, three ways to connect (USB-C, Bluetooth 5.2, 2.4 GHz), and a 4000mAh battery, so it works as a desk board and a wireless one. The ROG Falchion Ace 75 HE is the sharper gaming tool: 8000 Hz polling, 0.01mm actuation steps, an onboard adjustment wheel and a carry case, but it is wired only, Windows only, and drops the numpad. Build is close, with an aluminum top case on the Keychron and a compact 75% frame on the ASUS. Owners of the Keychron praise it out of the box and its customization depth; the main complaint is a short one-meter cable.

  • Choose the Keychron K4 HE if you want a numpad, wireless Bluetooth and 2.4 GHz, Mac support, and QMK firmware you can remap.
  • Choose the ROG Falchion Ace 75 HE if you play competitive games on Windows and want 8000 Hz polling, fine 0.01mm actuation tuning and a travel case.

Questions and answers

Which is better for gaming?
The ROG Falchion Ace 75 HE. Its 8000 Hz polling and 0.01mm actuation steps give finer, faster response. The Keychron K4 HE is fine for casual play but polls at 1000 Hz.
Which is better for office work?
The Keychron K4 HE. The number pad speeds up data entry, and Bluetooth lets you switch between a laptop and a desktop. The ASUS is wired and has no numpad.
Does the Keychron K4 HE work with a Mac?
Yes. It supports macOS, Windows and iOS, and QMK lets you remap keys for either layout. The ROG Falchion Ace 75 HE lists Windows 10 and 11 only.
Which has the better build?
Both are solid. The Keychron has an aluminum top case with an aluminum plate. The ASUS is a dense 75% board that ships with a protective carry case, which suits travel.
Is the ASUS worth stepping up to over the Keychron?
Only if competitive gaming on Windows is your priority. You gain 8000 Hz polling and finer actuation tuning, but you give up wireless, the numpad and Mac support.
Can I change the switches on either?
Yes. Both are hot-swappable, but each takes its own magnetic switch family: Gateron Dual Rail Magnetic on the Keychron, ROG HFX V2 on the ASUS.
