Aural or ETD, Which is Best? (kinda long)

A slight aside, but a few years ago when I was tuning strictly aurally a
potential customer called to inquire about my services.  He asked me if I
tuned aurally or with an ETD.  When I responded that I tuned aurally, he
said "thank you very much but I am looking for someone who tunes with an
ETD.  So go figure.
