The most recent prior to this new one is equal to blue and the plan before that is equal to green. I am very happy with blue because it's right in the middle with points and 0 point foods. Purple gets the least points with 300 0 point foods, blue has 200 and green has 100 with the most points. So green has flexibility to use points on anything (including foods that are not ideal) while purple requires really good portion control on 0 point foods and has less points that can be used for foods that are not 0 points. Look at each list, think about what you eat, your lifestyle, and your goals to determine what seems best for you. You can always try something for 2 or 3 weeks and switch if it doesn't work for you.
