Topre Realforce 104UB vs TypeMatrix 2030

Topre switches are a mix between mechanical switches and rubber dome switches. They have mechanical components, however they are covered beneath a rubber dome which protects the switch. They bring a mechanical feel, and mix it with the durability of a rubber dome switch.

Variable weights under each specific groups of keys was done in a bid to prevent RSI (repetitive strain injury). For instance, the groups of keys that the pinky finger hits are much lighter/softer than the rest of the groups of keys that are pressed by the rest of the fingers. Variable weights are achieved by having either heavier or lighter rubber domes. Whilst this idea is very useful for normal typing, for gaming it's not so great: for instance, when dealing with First Person Shooter games that requires WASD keys, those sets of keys feel very light when fingers other than the pinky are used to actuate them.

Silenced Topre switches are designed for those who do not particularly like the sound of keyboards being tapped on or for those who may be concern over disturbing others when using a noisy keyboard. Silencing is done mainly by placing a material that absorbs the sound of the slider when it makes contact with the slider housing. This thereby prevents excessive noise when the key has been released after it has been actuated. The overall effect of a silenced Topre is quite astounding as it may give the impression one is on a cheap keyboard (obviously, the reality is actually the opposite).

PBT (polybutylene terephthalate) keycaps last longer than other keycap materials, and are more durable. They are more expensive than ABS (acrylonitrile butadiene styrene), which is why they are less commonly found.

The matrix layout reduces the travel distance of fingers. The keys feature membrane switches with double-scissor substrate, which are quite comfortable and very quiet.

This keyboard has a small footprint, only 324 by 133 mm. This not only leaves more room on the desk, but also and mainly reduces the lateral travel distance of the right hand to grab the mouse. It still offers a good numeric keypad thanks to the matrix layout.

Numerous skins are available, making it simple to keep the keyboard clean and even quieter. They also allow for multiple layouts.

This keyboard's matrix layout allows for increased typing accuracy. It gets rid of the typewriter keyboard legacy in favor of a more logical layout.

These layouts are not easy to find, especially the first one. While they don't necessarily increase the typing speed, they greatly reduce the travel distance of the fingers, and have a much better distribution of the keys than regular AZERTY or QWERTY layouts.
