I have the UHK with Cherry MX Brown switches and my old MS Natural (105KB?) which I had purchased second hand.

I feel that my UHK keys require less force than the Natural.

My Natural has a bit more prominent click points (which require more bundled force at a certain point) but an overall "stickier/mushy" feeling (to be fair, I hadn't cleaned it a lot :)).

My UHK keys feel more springy and one might not particularly notice the click point but I still get good tactile and auditory feedback.

It took me about 2 days to get comfortable with the new keys. Overall the UHK feels smoother and less strenuous.

I hope you can make some sense out of the above, otherwise please feel free to ask for clarification :)
