I like comments without, I find myself focusing more on what's being said than skipping over folks with significantly less comments.
I've read criticisms about not being able to quickly/easily filter out top comments (which I care about, too). But there might be other (better?) ways of achieving that without reverting back to scored comments. For example, coloring/annotating comments that cross a certain threshold (either an absolute number, or relative to the other comments in the post). The advantage of color is that it becomes easier to visually filter out highly voted comments.
