Well, I usually end up being NG, perhaps with a small list towards CG. It's a pretty "easy" alignment to play, and when I do "alignment-type quizzes" I generally end up NG based on my answers. Otherwise, I'll go for CG, but I have to aply myself a little more to playing the chaotic part of the alignment.
However, I'd also like to chime in with the rest of you that said "I prefer alignment-less" gaming. I'm not all that comfortable with setting labels on people and things, calling them "good" or "evil". As I have grown older, I have begun to appreciate gaming that is more gray-scale than black or white. I like characters that are more like one of the heroes from a film noir, a scoundrel who, for unknown reasons, decides to do the good thing for once.
Cheers,
