Product 1: Logitech G512
No score yet
Product 2: NuPhy Air75 V3
4.7

ISO and JIS availability stand out as meaningful layout additions that broaden the board’s appeal beyond standard ANSI buyers.

legend visibility
Product 1: Logitech G512
3.2

Legend visibility is mixed. Main legends can look clean, but several reviews criticize secondary legends that do not light up or are unevenly lit on some versions.

Product 2: NuPhy Air75 V3
3.0

Backlighting is present, but one review says the stock caps do not let light shine through the legends well, which can hurt night visibility.

macro customization
Product 1: Logitech G512
4.0

Product 2: NuPhy Air75 V3
4.2

Reviewers like the material mix of aluminum and ABS, finding it premium enough for the price while keeping the board practical for a low-profile design.

media controls
Product 1: Logitech G512
3.4

Product 2: NuPhy Air75 V3
4.4

Media controls are easy to access through knob functions or software remapping, which adds day-to-day convenience.

noise level
Product 1: Logitech G512
3.5

Noise level is one of the main tradeoffs. Some switch versions are fairly controlled, but GX Blue can be loud enough to bother nearby people.

Product 2: NuPhy Air75 V3
4.2

RGB lighting is generally well-liked for brightness, effects, or appearance, though one review noticed uneven perceived brightness across rows.

size and form factor
Product 1: Logitech G512
3.8

The G512 is consistently described as a full-size, standard-layout keyboard. Some reviews like the compact deck for a full-size board, while others still see the numpad layout as bulky.

Product 2: NuPhy Air75 V3
4.3

The 75% low-profile form factor keeps the board compact and practical while still covering the keys most reviewers expect to use daily.

software quality
Product 1: Logitech G512
4.0

Software impressions are mostly positive for customization and usability, but not universally so. Some reviewers found vague icons, complexity, or buggy behavior in Logitech's software.

Product 2: NuPhy Air75 V3
4.2

4.5

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

stabilizer quality
Product 1: Logitech G512
3.8

The only direct stabilizer review calls them decent, though larger keys can still rattle a bit.

Product 2: NuPhy Air75 V3
4.2

Stabilizers are usually described as solid and low-rattle, especially on major keys, though at least one review stops short of calling them class-leading.

switch feel
Product 1: Logitech G512
4.2

Switch feel is a strong point overall. Reviewers liked the clicky GX Blue and other switch choices, though some switch variants were called scratchy or mushy, so feel depends heavily on the version.

Product 2: NuPhy Air75 V3
4.5

Reviewers consistently praise the switch feel as smooth, tactile or well-traveled depending on switch choice, giving the board a more satisfying feel than many low-profile peers.

switch options
Product 1: Logitech G512
4.3

Multiple reviews highlight three switch choices: Romer-G Tactile, Romer-G Linear, and GX Blue. That gives buyers meaningful options for clicky, tactile, or smoother input.

Product 2: NuPhy Air75 V3
3.7

Switch choice covers linear, tactile, and silent options, but multiple reviews still call the overall selection limited compared with some expectations or prior models.

typing comfort
Product 1: Logitech G512
4.3

Typing comfort is generally strong, with good spacing, comfortable use, and switches that can support longer sessions without tiring fingers too quickly.

value for money
Product 1: Logitech G512
4.2

Most reviews present the G512 as good value for its build, lighting, and switch choice, although some note it is not especially cheap in every market.

Product 2: NuPhy Air75 V3
3.9

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

volume control
Product 1: Logitech G512
3.5

Volume control is available through function-layer shortcuts, but the lack of a dedicated dial or separate buttons is a recurring complaint.

Product 2: 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.

wireless performance
Product 1: Logitech G512
No score yet
Product 2: NuPhy Air75 V3
3.3

Wireless performance is generally useful and fast enough, but a few reviews report isolated Bluetooth or dongle quirks that keep it from feeling flawless.

wrist rest quality
Product 1: Logitech G512
2.0

Several reviews specifically call out the lack of an included wrist rest, making this an obvious weak point at the price.
