Excellent Casts
1. ASS (Almost got the best cast possible from the first 7 seasons)
2. Marquesas (I think this season had some of our most complex personalities in Survivor history)
3. Cook Islands (Gave us the best characters of post-ASS)
4. Fans vs. Favorites (Even with the super fans who weren't so super the favorites were truly an all-star ensemble)

Great Casts
5. Amazon (Had a lot of entertaining castaways and Rob C. was perhaps one of our best commentators)
6. China (People were either duds or stand outs and the 2nd group outnumbered the first)
7. Fiji (Casting did a good job picking people with lots of personality and attitude this season. Great mix of people)
8. Pearl Islands (Like Fiji did a great job with getting a ratio of people to root for and against and plenty of personality)

Good Casts
9. Exile Island (Had a good mix of people of different ages and great characters in Casaya)
10. Gabon (So far has a great mix of spunky castaways with interesting backgrounds)
11. Borneo (Had some of our most interesting older castaways in Survivor history)

Average Casts
12. Guatemala (Steph and Bobby Jon were developed already thanks to Palau and the merge castaways were pretty interesting)
13. Palau (Had lots of duds but its large cast gave us lots of characters to work with)
14. Vanuatu (The women were very interesting this season and made up for the boring men)

Poor Casts
15. Africa (Had no real strong characters who were truly provocative. Those that had potential weren't really likable either)
16. Thailand (Not the most interesting group to begins with plus the duds ended up taking over the game)
17. Outback (The most boring group by far with only Maralyn, Jerri and maybe Colby having some personality)
