I’m happy there’s such a variety. I guess I tend to prefer some texture to avoid the racing-slick effect I get with otherwise gorgeous smooth caps like SP SA - but rough texture less so. I brush my thumb on the spacebar, and really smooth ones are too grippy on my thumb and throw me off.
My favorite right now is MT3 (funny because it was planned to be smooth and the factory was like “woops well that’s how we made the tooling”) - it has enough surface variegation for my clammy hands not to grip too much, but the peaks and valleys of that texture are more round than sharp - just right.
I like the dry, almost boney feel of bare, pure PBT - but aforementioned clamminess makes the commonly used coatings feel… extra clammy.
