Ho Ernani.  I too prefer to listen to Gigli rather than Caruso.  Although I saw Gigli right at the end of his careeer, his voice still had that "golden centre" that makes a voice really attractive.  Another tenor I feel was under appreciated outside Italy was Ferruccio Tagliavini.  On record (78rpm) I have never heard Una Furtiva Lagrima sung so perfectly, with a "swell", ignored by other tenors who sound, to me rather superficial.  A baritone ,almost totally forgotten, was the large, clear voiced Paulo Silveri who could make the gas brackets in the "gods" rattle with an inserted high baritone Ab.  For breath control and true bel canto (not can belto) the baritone Giuseppe de Luca is still, in my opinion, the best of the last 100 years.
I could go on, I'm afraid, but personal preferences in all but small doses can become boring.  Monaco's voice was superb and greatly to be admired - but, again, in small doses.
Cheers 

Ho Ernani.  I saw him in one of his last recitals.  His voice was still a beautiful lyric instrument and his manner was fairly still on the platform and with an ease of approach to his highest register that involved only a slight forward drop of the head and jaw coupled with a slight leaning backwards.  He came over as a pleasant, easy to listen to, modest performer and one who communicated easily with the audience.  I heard that after the recital his immediate concern was to ring back to his farm to enquire into the welfare of a pregnant sow.
Cheers

Ho!    Your mention of this thread on another thread made me think that you might be interested to learn, and please don't be embarrassed, that I've sung "you" thirty nine times.  Your first Act is a real goer.  I always enjoyed you. Oh!  Sorry, pardon.  Why did you pick Ernani for your name?
Cheers

One can only hope that he meant it literally.
