When it comes to CDs, I definitely prefer otome content. With manga or anime, though, I often end up preferring BL depending on the relationship between the characters.
It depends on the situation, but when I want to relax, I prefer all-ages content. That said, I don't mean something completely wholesome—I think it's best when there are slightly sensual touches, such as soft, alluring breaths during an ear-cleaning scene.
At least when it comes to the heroine's voice in otome titles, I disagree, since I tend to self-insert when playing those kinds of games and therefore prefer the heroine to have as little defined personality as possible.
