Here is a force-displacement curve for Topre switches:
And here is a force-displacement curve for a Cherry mx switch, the "clear":
I like the fact that Topre switches have a decrease in force after the actuation point. In contrast, Cherry mx switches have a continuing increase in force after the actuation point. The slope of force vs displacement is especially high in the mx clear switch. I tend to bottom out my keystrokes, and so I find mx clear switches rather fatiguing. Topre switches provide tactile feedback while being more relaxing to use.
In fact, to me, Topre switches feel a bit like playing a real piano. This sensation is not nearly as pronounced in a Topre switch as it is in an IBM beam spring, but the subtle sensation is there.
To put this into perspective, I would rank switches I have used roughly as follows:
IBM capacitive buckling spring (Model F) > Silenced Topre 45g ~ Silenced Topre 55g > Topre 55g ~ Topre 45g > IBM membrane buckling spring (Model M) > Orange Alps > Monterey Blues> White Alps > Matias Click > Matias Quiet > Space Invader Clicky > Space Invader Tactile >>> Cherry mx (Brown > Green > Blue > Red > Black > Clear).
