If you are going to programme the FMGS, then let it do its thing the way your employer wants.
If the flight director is on, then follow it, otherwise switch it off! The link between FD and A/T is pretty tenuous, try an engine failure in ALT*, and see what the priorities are!
Flying faster means you can do more sectors, or more days of work...hmmm.
