What is the difference between ReΛlforce and Real Force keyboards? Why do they have different names?
I personally believe they refer to the exact same company unless someone is trying to produce some mock up keyboards using "Real force" naming.
The company is meant to be called "Realforce" but they have used a fancy character to differentiate themselves by saying that they are "ReΛlforce". The "Λ" cannot be easily reproduced when say for instance in the context of chatting for instance, plus there are some machines that are not capable of rendering the same "glyph" hence for simplicity sake "ReΛlforce" is referred to as "Realforce".
I guess personally some people refer "Realforce" or "ReΛlforce" as "Real force" or "Real Force" is probably because the natural way in say for instance when using English the need to use spaces are apparent. "Realforce" is not an English word, "Real force" and "Real Force" may seem more appropriate as an English word even though "Real Force" is basically captalising two letters. Different people may refer to the same brand names differently. Some people even say "Microsoft" as "MicroSoft" or "Micro$oft"; "linux" as "Linux" or "GNU/Linux", etc. Different people have different ways of addressing things but I am sure they mean the exact same thing unless later on they prove they were implying something else.
Now back to the topic of Topre and HHKB, I personally would not say that it feels like a rubber dome keyboard. Sure the conical spring sits inside of a rubber dome in which when the user normally presses a key the rubber is the one that is mostly felt on the way down. However on the rebounce I believe the conical spring provides an extra feedback to the rubber dome. Besides both the conical spring with the rubber dome sits on top of a hard PCB. Not those flexible membrane boards which heavily depends on how hard one tightens the screws on the bottom of the keyboard. It is not easy to describe the feeling but declaring Topre as nothing more than "glorified rubber domes" or "rubber domes with a spring", etc is both wrong and aren't the exact best ways to describe the feeling of typing on Topre.
The best way is to really try the switches out yourself. You can read as many information scattered online as you like but they are mostly opinionated answers. The actual feeling when one tries it can be simply summarised as how a picture describes 1000 words. Maybe that is a bit of an exaggeration, but maybe around 800 words or so. Though again what comes out in a text form is still based on a person's personal perception which others may/may not agree.
There are no real losses when trying out Topre, you're (OP) living in a country where I am sure there are plenty of buyers whom will want to source a Topre board that was pre-loved should you find the switch is not suitable for your needs. Plus getting one brand new is not as expensive as say for instance if one were to be based in Europe.
Last but not least, I want to point this out...
