You know, after reading this thread, I still don't understand what makes the Topre switch so great ... 
1. Is it quieter than a brown cherry?
2. Is the landing softer than a brown cherry?
3. Is it more tactile than a brown cherry? Clearly more or comparable?
4. Is it lower force than a brown cherry?
based on my minimal experience with both, re: the topre, I'd say two things jumped out at me when I used them:
-the sound. the sound of typing on it is kind of unique in the keyboard world I think, its a "thock thock thock" that I havent really heard anywhere else. I mean its not particularly special in itself, but its different, and its not unpleasant.
On a practical level, the sound was 'not too loud, not too soft', making it something you could use in an office setting while still enjoying some auditory feedback.
-the second thing that jumped out at me was the clearly high quality construction, the tightness of the keys (no wobble), smoothness of the stroke (extreme smoothness), and velvet landing of the downstroke (its not a hard or loud landing, and not a mushy/membrane feeling landing, its in between, literally like landing on velvet, is the closest description i can come up with - and again it was unique, different from the two extremes we're usually used to (hard/mushy).
To answer your questions individually:
1. Is it quieter than a brown cherry?
I'd say no. but its not as loud as alps or bs, its totally useable in mixed company.
2. Is the landing softer than a brown cherry?
i'd say yes, but not mushy.
3. Is it more tactile than a brown cherry? Clearly more or comparable?
this is a hard one. Topre felt linear to me but people tell me there is supposed to be a slight tactile bump or hump. When you type fast tho you wouldnt really notice (i didnt). but in that theyre simlar to browns where if you type fast you barely notice the tactility. so maybe a little less of a tactile bump on topres. They mainly felt smooth-linear to me.
Maybe if you took away the very slight bump i'd notice that it was gone, i dont know. but i didnt really notice that it was there.
4. Is it lower force than a brown cherry?
I'd say no. the cherry browns felt way too light to me, whereas the topres felt neither too light nor too hard.
Looking at my answers, I guess if there's one theme that emerges about the topre, its that they're a 'goldilocks' switch, apparently. Neither too hot nor cold, neither too hard nor soft, neither too loud nor quiet, etc.
Keep in mind though I'm doing all this from memory. I owned a brown cherry board for about a month, but only tried the topre for about 10 minutes in a starbucks.
Maybe others will give you different answers.
