Puccini operas are generally my favorites, and Kiri Te Kanawa my favorite soprano. Others are excellent, but for me at least, her voice had a quality unmatched. Similarly, I prefer the quality of Andrea Bocelli’s voice above that of the late great Pavarotti. But there is no question that Pavarotti was the superior tenor. His clarity and accuracy were wonderful, imo.
OTOH, I do disdain arrogant jerks who imagine no one else’s opinion can possibly be as “important” as theirs. Hopefully you have managed to absorb that.
No one else even comes close!
Another vote for Kiri!
You need to lie down in a dark, quiet room with a cool cloth across your fevered brow. You are too nervous a creature to discuss the career of Jackie Gleason with the dispassion it so obviously deserves.
