Score breakdown
Switches & typing
The key switch technology; later types are generally more responsive.
The specific switch used (e.g. Cherry MX Red).
The force needed to register a key; lower is lighter to type on.
Swap switches without soldering.
Registers every simultaneous keypress.
Set the actuation point per key (analog / Hall-effect boards).
Keys report their travel depth for variable gamepad-style input and multi-stage actions.
Performance
How often the keyboard reports input; higher can reduce latency.
End-to-end keypress latency over a wired connection; lower is better.
End-to-end keypress latency over the fastest wireless mode; lower is better.
Resets a key dynamically as it moves, enabling faster repeated inputs.
Layout & size
The keyboard size and layout.
The number of keys.
The overall width.
The overall depth.
The front case height without keycaps; lower boards can reduce wrist extension.
The keyboard's weight.
Connectivity
The supported connection types.
How many paired devices it can switch between.
Battery life for wireless models.
The rated capacity of the internal battery.
A built-in USB port for other devices.
Build & sound
Keycap plastic; PBT resists shine and wear better than ABS.
The case material (e.g. aluminium, ABS plastic).
The switch plate material, which influences stiffness and typing sound.
How larger keys are stabilised (e.g. screw-in PCB or plate-mounted).
The plate / PCB mounting style (e.g. gasket mount).
Internal foam or dampening for a quieter, fuller sound.
The per-key lighting.
Features
Remap keys and record macros.
Dedicated volume and playback controls.
A control knob for volume or custom actions.
Stores layouts on the board itself.
Companion configuration software (e.g. VIA / QMK).
