It was playing with @arnoldkim's Das that got me to jump off of the Matias Tactile Pro v1 I'd been using for 7 years or so. He has a Das brown and I grabbed a blue. I quite like it. He wanted a tenkeyless brown keyboard (we both got Realforce 87U's after the Das), so he got a Filco with browns. His impression was that the Filco would feel much better in build quality than the Das, as the Topre board made the Das feel cheap in comparison (I agree with this).
The Filco arrived and I was curious to hear how much of a difference in quality the two Cherry boards demonstrated. He was surprised to report to me that they are much closer in feel than he had imagined. The Filco feels slightly nicer, he indicates, but it's slight. So, they're pretty much the same. I ceased contemplating the purchase of a Filco, with that news.
And, out of the blue sky, I ordered a buckling Unicomp. Go figure!
(I am pretty sure I'll keep with the Topre as my main, preferred board, it feels so nice.)
