Some of the best rubberdomes like the Keytronic, Chicony, Dell's RD, while very tactile and almost not mushy, they still don't feel exactly like Topre's. The Topre, after overcoming the 'bump' on top, just collapses into emptiness. No resistance, and almost no spring pushing up against the finger. Because it's capacitive, and physically touching nothing, it slides smoothly as butter. Rubberdomes never behave like this. Actually I still kinda like the good rd's. Cheap and good enough for writing. Soft cushioning and springiness from the dome. Lasts a good few years, maybe a decade use.
But still, Topre is in a whole other league.
I may compare it to driving a Ford Focus mk1 or a Honda Civic EG6 to a Mercedes Benz S Class. Whole the former two are very good cars, with excellent road feedback and reliable. Still it doesn't roll as smooth as a Merc. Both are still excellent.
