If I had to choose, it would be Heather. Reasons being:

1. She lasted longer than anyone else in the competition (with winnning TDWT being the best moments before the original cast is replaced). In this case, she ranked 1/25.

I'd have to agree. Heather was the main antagonist of the first two seasons, and was the person that made the competition interesting.
