Well, I have both Blue Cherries (Das) and the Topre 103UB (55g). I recently bought three keyboards to test out because I couldn't make up my mind, and I finally just got fed up and decided the only way to find out for sure was to actually pony up and buy three of the major switches on the market today. So I bought a Das, a Topre and a Unicomp Space Saver Buckling Spring. I may post a review soon comparing all three, once I've made up my mind which I like best.
My background and experience has only been with cheap rubber domes. So I don't know if my impressions would mean more or less to you.
The Topre switches, like others have already commented, are the most like rubber domes. But very well-built rubber domes. They seem to travel slightly further than most rubber domes, but instead of a mushy landing at the bottom, they are firmer and want to spring back up a bit more. The keycaps have about a 1-2 ml smaller surface area than standard keycaps. I'm not sure if this has anything to do with Asian design for smaller finger tips, but it was something I noticed. They keys do not wobble or have any side play, as on some cheap keyboards. They go straight up and down. There is definitely no 'click', no actuation point, no bump, no buckle, no snap --- just a smooth descent down... and then back up, like a bungee cord. Because there is none of the aforementioned, a heavier (55g) keyforce weight helps somewhat with the tactile feel. However, make no mistake, the Topre is NOT a mechanical keyboard in any sense, as there is almost no kinesthetic feedback. The black keycap model I bought has letters which are almost invisible under ordinary light. They are essentially blank. But if you squint or look at the keys at the right angle, or have brighter light, you can make out what the letters are. I haven't made up my mind about the Topre yet. It is definitely as quiet as any standard rubber dome, perhaps ever so slightly more audible given its 'thwocky' sound.
If you like blue cherries, I mean really like them, ( as you state) my instinct is to tell you the Topre switch probably won't be your cup of tea.
Hope this helps.
