size and form factor
Product 1: Keychron Q3 HE 8K
4.5

The form factor is positioned as compact or 80%, making it practical without being a full-size board.

Product 2: Razer BlackWidow V4 Pro
2.4

volume control
Product 1: Keychron Q3 HE 8K
4.5

Volume control is a clear strength thanks to the physical knob and remappable knob functions.

Product 2: Razer BlackWidow V4 Pro
4.4
