Is it so hard to accept that there are different ways of using a computer and your perceived increase in efficiency might not pan out for everyone? :)
The thing is, we have studies that prove that mouse + keyboard interaction is faster than keyboard-only https://www.asktog.com/TOI/toi06KeyboardVMouse1.html - until you become super proficient with all the relevant the keyboard shortcuts.
So it's not about "inferior"/"superior", it's about your use case.
Even if there were a significant difference one way or the other, it's rare to spend more than 1% of your time arranging your workspace and switching views & windows, so any optimization of that 1% will have minimal effect on your productivity.
