Drew,
Like other things in life, one often must make compromises. That
compromise would ideally be made based on your preferences and with
knowledge of what is best for certain conditions.
We know that low pitches are better for the brain to separate two
different pitches (a signal in QRM), and we also know that very high
speed CW operators like a higher pitch because it is easier to discern
the code elements. If you belong to either group, your choice is
obvious, but I believe for most, the compromise using the Elecraft
default of 600 Hz makes sense - but you can change it for any reason if
you have a desire to do that.
I have heard that weak signal operators (i.e. EME) like to use a wide
bandwidth, but I have not heard about a preferred pitch.

Now what about weak signals in noise (no QRM): any idea which pitch is
better there?
And I wonder about keying speed (element length): a shorter element
must carry better at a higher pitch I would think.
Of course, it doesn't matter much if your own ears have a problem with
the theoretical best pitch, i suppose.
