I've tried several different varieties of "mechanical" keyboards, including buckling-spring keyboards, and I've come to the conclusion that I genuinely prefer laptop-style keyboards that have a hard stop for my fingers. (Specifically, I type on ThinkPad keyboards, even on desktops and docked systems; I use USB ThinkPad keyboards, complete with the mouse on home row.)
I don't type "through" the hard stop; my fingers know to stop right at the hard stop, but I prefer a physical stop rather than just a change (subtle or otherwise) in the amount of pressure I have to apply. I also like the very small amount of travel in the key.
I'd sort of agre with this, I find I type fastest these days on my bluetooth apple keyboard but my personal favourite is still my TiBook semi-trsnaparent keyboard, it had a comfortable amount of travel and great action.
