I love both but I'm not a trained singer, so I'm less knowledgeable about the human voice than a lot of the folks that spend most time in the opera forum. Recently I've been taking a bit of a break from opera, as well (not a complete break, but a lot less than I used to consume) which probably affects my perception at this moment. I'm a bit unusual, I think, in that I came to opera somewhat knowledgeable about the orchestra but not very knowledgeable about the voice. I've been trying to learn what basics I can but it's still somewhat of a handicap. That said, I'm a novice when compared to the people who frequent that forum, but I still know a decent amount. And I'm always trying to learn more. That's what life is for. I don't see opera and classical music as distinctly "different" things, but they are slightly different art forms, I concede. There's enough overlap that I don't really think about them as different in my own mind.
