I now have 4 Topre boards (2 87Us and 2 HHKB) and am looking to try some more Topre keyboards.
Topre is certainly rather uneventful. If you're looking for a new and exciting typing feel, it won't give you that fuzz the way some buckling springs or clicky Alps do (which is why I have those too!).
However, of all my keyboards, Topre 45g is the one that I can type on endlessly without fatigue or discomfort, while not making any annoying/overly loud sounds. I absolutely love the way that they sound (unsilenced) and the keycaps tend to be well made with a nice texture.
I especially love the tactility of the Topre switches as it's an elongated hump. It's not dramatic, but because it occurs over such a long portion of the stroke, you end up still feeling tactility when typing very quickly. By contrast, my Blue Alps, MX Blue, buckling springs, Zealios Purple, MX Clear, and especially MX Brown -- ALL feel as near as makes no difference to linear when typing quickly (though not as nice as actually typing on linears, which I love). The slower you type, the more all of those switches can be felt (especially my beloved Blue Alps, which have a longer tactility than MX Blue).
I get that it won't be for everyone. I certainly didn't start off with them because they seemed boring, and in a way they really are...
I really think they "Lexus" comparison is rather fitting since Lexus is rather boring and uneventful... nobody really gets excited for them, but they're very nice and most people could drive one around all day and be happy -- but it won't satisfy that thrill.
They even last forever and hold their value like a Lexus
Next up is HiPro and maybe 30-35g Topre as I'm curious what they're like.
