Topre Realforce 104UB vs KB Paradise v60

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 keyboard backlighting color can be set to either green and blue or red and blue. This option can be switched on the fly.

The 60% form factor means your hands almost never have to depart from home row for any reason, increasing efficiency.

With this keyboard, there's a wide variety of switches to choose from. From practically all Cherry switches to cheaper, non-backlit Gateron or Matias switches.

This keyboard is built to last.

The keycaps are typeset in Futura, arguably a more attractive option than what many similar keyboards (such as the KBC Pokers) feature.

The v60 has six DIP switches on the back that allow for a variety of layout customization options, and the keyboard comes with extra keycaps to reflect those options, so that the inscriptions always match the key functions. Some examples include replacing Caps Lock with Ctrl (a popular trick for programmers, as some Unix software was written with such a layout in mind) or swapping left Super and left Alt to accommodate users used to Apple keyboards.
