The whole concept of a "good" figure can't be considered in isolation. Were Possette or Miki 2 good figures when released? If a new user asked you now to recommend a good figure would you name either of these? We can also see from these posts that many people have different ideas as to what makes a good figure, from technophiles whose main concern is how technically correct the figure is to the figure artists whose concern is how every body part looks in any pose. IMHO the way to judge if a figure is "good" is if lots of people want to use it, and for which vendors find it easy and rewarding to create content. These two are of course linked, I don't think there is any magic formula, for success the figure has to attractive out of the box, well advertised and promoted, and the timing must right. And of course it must not be so "out there" that content creators can't easily work with it. Looking at recent figures, Pauline/Pauline, PE and LaFemme you only have to look at the number of products in the store to decide which are "good" figures.
