If the stem is flipped, thus lower, even riding on the top of the bars or hoods will be more aerodynamic than if the stem was in a higher hi-rise position.
Just because your hands are on the drops does not mean you are in a cleaner aero position, All the drops do is lower your frontal area, however it does create drag as well because your arms are out to the side.
The most aero dynamic position on regular drop bars is with your hands close to the stem in a praying mantis tuck. This combined with a lower stem creates the least aerodynamic resistance. You notice in the TdF as they descend the Alps or Pyrenees, they all take this position.
It's not only "Aesthetics value only" because lower is lower, however I agree, there is a balance point, that only you can determine whats right for you be it speed, comfort, looks.... etc.
Like I said, ride to your own level be it Geezer or Racer
