As many already pointed out, the "keyboard vs mouse" debate is, somehow,
useless. It's actually the application you use to be made to use the
keyboard and mouse in a efficient manner.
The most productive applications I used (in general, for the jobs they were
intended) were Blender, Labcenter Proteus suite and SolidWorks. Why? because
they were really engineered to be efficient with both the mouse and
keyboard. Also, the Blender interface is also very flexible so you can have
on the "desk" what you need and when you need. They were simply made to give
you a feeling that the keyboard and mouse makes a good team.
And I can point the worst application I ever had to use to be Cadence Orcad
Layout version 9.2/10 (I didn't bothered to use a newer  version because the
harm was made). This one has long and deep menus, hard to remember shortcuts
and simply you couldn't prioritize the interface to have what you need when
you needed it. Yes, they were very organized based on some criteria, but my
criteria on arranging things is based on frequency of use. And the keyboad
and mouse are something that doesn't belong to the same team in this
application.

My conclusion is that not the keyboard, not the mouse sould be condemned.
It's all about how the application/user interface is engineered.

P.S. why nobody says anything about touch-pad? this may be in some cases
more efficient than mouse or keyboard. On my laptop I have scrolling arreas,
and different tapping combinations to routine tasks with wich I feel
so productive that I bought a keyboard with touchpad to my desktop computer
