One long-term review specifically notes low rattle on stabilized keys, suggesting stable key behavior in day-to-day use.

Product 2: Logitech G915 X Lightspeed
4.2

Key stability looks improved overall, though one review still notices a minor wobble.

latency
Product 1: NuPhy Air75 V3
4.4

Latency is treated as low enough for responsive wired or dongle use, but the board is still framed as casual-gaming friendly rather than esports-first.

Product 2: Logitech G915 X Lightspeed
4.8

Wireless latency is repeatedly described as very low and close to wired behavior.

layout options
Product 1: NuPhy Air75 V3
4.7

Product 2: Logitech G915 X Lightspeed
4.7

Review coverage confirms both full-size and TKL layout options in the lineup.

legend visibility
Product 1: NuPhy Air75 V3

sound dampening
Product 1: NuPhy Air75 V3
4.5

Gasket mounting and internal foam are repeatedly credited with reducing hollowness and harshness, materially improving how the board sounds and feels.

Product 2: Logitech G915 X Lightspeed
3.1

3.9

Reviewers generally feel the feature set justifies the price, but several also note that it sits above some competing low-profile options.

Product 2: Logitech G915 X Lightspeed
3.3

The feature set is strong, but the premium price keeps value mixed rather than an obvious win.

volume control
Product 1: NuPhy Air75 V3
4.1

Volume control works out of the box and is widely mentioned, though some reviewers criticize the knob’s wobble rather than the function itself.

Product 2: Logitech G915 X Lightspeed
4.7

The volume roller or wheel is one of the most consistently praised physical controls on the board.

wireless performance
Product 1: NuPhy Air75 V3
