The autobrakes will always do a better and more consistent job of applying the brakes than you.
Rubbish. 
For a start, maximum manual braking is stated in the manual as being better than the "MAX" setting on Boeing autobrakes. Any pilot aware of the tendency to favour one foot over the other and who takes a bit of care can do a better, more consistent job of braking than an automatic system. Finally - relying on autobrakes has led to at least one major accident in a 747 at Bangkok.
