As anyone who is familiar with the force graphs of tactile and linear switches (or has used both of them) is aware, the feel of the keyswitch is completely different between the two. Even between, say Cherry MX Browns and Reds, which have the same actuation force, the feel of using each switch is completely distinct from the other because the finger must exert its force upon the key in a very different way.
So, which do you believe is the more "natural" type of key action? Is linear more natural because of its smooth, constantly increasing force curve, or is tactile more natural for the fingers due to the presence of the "bump" to let the fingers know when the switch has actuated? Which is more conducive to efficient, high-speed typing? To those who have used both, do you find one type of switch to be more fatiguing than the other?
Welcoming opinions from those who have any kind of anatomical or physiological perspective, as well as those who simply have personal experience using both types of switches.
For my own part, I used browns (Leopold) for over a year and recently started to try reds (Filco), and have found the switch to be very interesting. I am still undecided as to which I prefer. When I read about reds prior to purchasing them and looked at the force curve, they seemed to be to be the obviously superior choice from a theoretical/logical perspective (i.e. the fingers don't need to "predict" the presence of the tatctile bump, they can simply push), but now that I am using them, I find I miss the tactile feedback quite a bit. Perhaps once I have gotten used to the reds, this will no longer be the case.
