I recently received the Topre Esc Key as part of Mr.Interface's worldwide sinklist. My reference is the cherry blue switch from a Noppoo keyboard as well as a lifetime's worth of keytronic experience. However, there's really not much to say about the switch itself.
Essentially it behaves just like a rubber dome. In a blue cherry, no matter how fast or slow you hit the key there is a well defined point at which it clicks. After this, there is still a few mm to travel before bottoming out. This is the greatest difference between cherries and rubber domes that I have come to appreciate.
Rubber domes, on the other hand, behave differently. If you push the key fast you get a bump (which is more spread out and not as sharp as a mechanical) and almost afterwards you bottom out. This is unavoidable as that is how the rubber dome collapses. If you push it gently, slowly, the dome will gradually deform and there is no bump. So there is no way to 'float on the clicks' like with cherry blues, e.g. type only by clicks without bottoming out. You have to bottom out with a Topre.
What makes the Topre better than other membranes? It has a deep travel distance. Other regular height rubber domes still have a short travel distance, and the keys will often rattle at the top. The key in a topre is always in contact with the rubber and throughout the entire key press you are always in contact with something giving you force feedback. I would like to try a full keyboard with these switches.
However, full height keytronic rubber domes behave almost exactly the same.
As for whether they are better or not than clicky switches, it's hard to say. Some people may appreciate a more smoothed out bump, while others may prefer a sharp, well defined point. I can see why people who game or type a lot would like the keyboard, as the keys probably help you when you are typing fast since they are softer.
