When I rank the packs I usually don't look at the world or items that come with the pack. I look at the gameplay and how much I enjoy that gameplay.
Without using that chart my rankings are:
1. Island Living
2. Snowy Escape
3. Seasons
4. Cottage Living
5. Get Together
6. Discover University
7. Get To Work
8. City Living
9. Cats & Dogs
10. Get Famous
11. Eco Lifestyle
Using that chart my rankings are:
1. Island Living
2. Cottage Living
3. Get Together
4. Snowy Escape
5. Seasons
6. Cats & Dogs and Discover University (tied)
7. Get Famous
8. Get To Work
9. City Living
10. Eco Lifestyle

Since Seasons does not come with a world I wrote N/A and gave it an average score of 6 so as not to penalize the pack for that. When ranking CAS for Island Living and Get To Work I looked only at the clothes and hair for human Sims so as to make it more fair to the other packs that do not include items for the occults included in these packs.
I am not surprised that Island Living came out top since there is so much that I like about that pack and I was expecting Eco Lifestyle to still come last since nothing in that pack appeals to me at all, but it is interesting to see where packs can move in the rankings based on using different ranking methods.
