Mzi's big jump is as a result of him moving above Zayn in the challenge performance rankings. That, combined with the fact that he had fewer votes against his name than Vanessa results in him moving above her.
Final Thoughts
So did the best survivor win? To some extent, that depends on your definition of "best".
There's no doubt that Gareth was the best when it came to challenges, winning more individual immunities than anyone else. However, winning challenges is not the most important thing, and Gareth's dominance was a factor in his being voted out.
After Gareth, the next best at challenges was Jacinda, who also only received one vote against her. So if you were to pick the "best" survivor, it would probably be Jacinda, who as we all know, didn't win.
