I have one of these, and while the switch tech is certainly neat, I haven’t really come up with many good ways to use it.
Their implementation doesn’t seem to support changing resistance or being sensitive to multiple levels of pressure on the key, but one way I do use it is by changing the activation distance for certain keys that I tend to press by mistake when gaming, like caps lock, so that you really need to bottom out the key to activate it. This seems to help a bit but I suspect that if I wanted to get the most out of it, I would probably need to be a much more intense gamer.
