Not sure whether this have been hammered in enough, but ultimately the issue of topre vs cherry, is more of an issue of personal preference more than anything else.
That being said, objective factors that sets them apart that I can identify are:-
1. Topre doesn't have option for clicky (ie. sound at trigger, as opposed to bottom)
2. Topre is not as loud (in fact it sounds different, and some people live and die by the topre "thock")
3. Topre is smoother, and strokes where the force is applied at an angle is directed downwards better.
4. You will bottom out with Topre, most people who use topre bottoms out, you just do (I have yet to seen anyone type at 100+wpm on topre without bottoming out)
5. I havn't have my topre wear down on me yet, (3 years and counting, heavy usage daily), but i wouldn't be surprised if topre last less than cherry considering the mechanism involved, and i think their spec is also stated to be less
6. From my experience, topre keys weights are much less uniform than cherry, even if its stated to be all 45g (eg hhkb), they can vary significantly, at least much more than cherries, likely due to it being a rubber cup and not a spring (the spring is mostly for activating the switch, and only offer 5g of force).
7. Topre is a pain if you are looking for key caps to replace
If you are looking to justify the price of topre, don't bother. I think a lot of people come here and think wow cherry is superior to rubber dome, i wonder would topre be the same leap above cherry (it certain costs that much more), and I think the answer is simply no. Despite all the above factors listed, I think preferences for topre and cherry for most people just boils down to feel (do you prefer a linear spring (possibly with a bump), or a super smooth bell shaped bump).
Take my case for example, I type on topre exclusively for 3 years, and I STILL type faster on a cherry brown whenever i go on my brother's keyboard, but I just can't give up the smoothness. The speed difference i attribute mostly to bottoming out (just FYI, i type about 110-120 wpm, and can peak at 130+)
