Typing switches? I'll throw a nomination out for Cherry MX Blue, and another one for Topre just 'cause. Out of the four switches I've tried, those two are probably the most suited for typing.
Cherry's MX Blue design is not bad. I really like how the tactility is
just present enough for me to know when the keypress registered without being too distracting and how the actuation force is
just high enough to keep me from bottoming out without making my fingers feel tired. Really easy to type on. If the click sound was more refined and the hysteresis wasn't as long as Sarah Jessica Parker's face, it might've placed higher on my acquisition list (the Ducky Shine 4 I tried them on was on loan from a friend).
I'm currently typing on a Novatouch with 45g weighting. The total lack of scratchiness, 1mm operation point and fast key bounce make for a really nice key feel, but I don't know if the tactility of the 45g domes would make for the absolute best experience for typing--It's really soft. I'd describe it as more of a tactile "hill" rather than a "bump." The dip in force past the peak makes it nearly impossible to not bottom out your keys. It's great as a daily driver, though.
I'd really like to get my hands on a Matias click keyboard. I think those would be great for typing on. Other dream typing switches would probably include Alps SKCM Blue, IBM Capacitive Buckling Springs (Model F), and IBM Beam Springs (loving solenoids for clickers? Holy stuff!).
Next keyboard is currently a tossup between this
Leopold FC980M in MX Red and
another KBP V60 in Matias Clicky flavor.
