> how many actions it takes to achieve something

This is not really objective because you also have to take into consideration how intuitive/simple the UX is. Given 100 related actions, clicking through a logically grouped nested menu or multiple pages to do something is going to require more steps but be something anyone can do. Memorizing and using keyboard shortcuts for all those actions will be more efficient, but isn't something someone could immediately do. There is of course an in-between where you can have menus to display available keyboard shortcuts, but some (most?) people will still prefer a GUI/mouse-based approach. There is no one-size-fits-all approach.
