IMO Kim played the best game ever for a first-time player. That's why One World was so boring. So self-aware and capable socially/physically/strategically, she knew what she was doing the entire time. I really would like to see what she could do in an All-Stars scenario.
One World, South Pacific, Redemption Island, and Caramoan are all pretty terrible. I never want to see Special agent Phillip Sheppard or Brandon Hantz ever again. The amount of screen time that went to those two in each of their seasons was embarrassing.
Micronesia(The first Fans vs Favorites), Heroes vs Villains, Borneo (season 1) are widely considered the best seasons. Cagayan is probably my personal favorite.
EW ranks the seasons every time a season finishes.

They had the Borneo and Micronesia tied for 1st. Second chance at #5.
You can really see the difference between Spencer and Jeremy in the final. Spencer is always talking about being a more open person, but still comes across like a robot. Jeremy was able to show those emotions, and connected with the jury better. Spencer did the exact same thing he criticized Woo for in his first season by taking the best player. When he flipped on Stephen, he did became the new Stephen, as mentioned earlier.
