Moreover, I've seen people move the mouse faster than I could achieve
the same task by keyboard.

To me, the advantage of ergonomic layout is not about speed - I'm sure
there will always be people able to type blazingly fast on any random
layout - but about comfort.  Even when typing slowly, I don't want my
fingers and my hands neither moving much more nor contorting much more
than necessary.
