Tactile feedback is not the Topre's strong suit.
Agreed. The Topre switches definitely require a lighter touch than Cherries IMHO. I almost sold my 87U (variable) a few days after getting it when my typing accuracy took a major nosedive since I was used to typing on Cherry Blues pretty much daily for the last few years. I found I was accidentally hitting adjacent keys a lot due to the softer resistance and the fact that you don't have to push the keys very far at all to activate the capacitive switches. I did change my mind, though, and gave the Realforce a second chance, and after about 10 days or so, I started to get the proper rhythm for the lighter keys and the board grew on me to the point where I decided to keep it. I still can't type walls of text quite as fast on the Topre as I can on a board with Cherry switches (or buckling springs) but it is definitely a more relaxing, lower-force typing experience if you slow down enough so that you're not bottoming the keys out too hard.
So I'd say the decision really depends on your typing speed and style. I agree with itlnstln that Cherries seem to "spring back" between key presses more than the Topres do, so in my experience, if you're usually flying along, banging out tons of text as quickly as possible, they tend to be less fatiguing. If you're doing more stop and go editing, repeated key presses, coding, data entry forms, etc, then I think the Topres are definitely more relaxing. And if you share space with coworkers, they are still quieter than Browns even if you bottom out. (If you slow down and try not to bottom out, they are nearly silent.) That said, I find that a good quality board with Browns is actually quieter than cheapie standard issue rubber dome boards, just due to the lack of key rattle, flexing noise, etc.
