First the worst, second the best.
Marvin Cortes, Cycle 20
Marvin's photos were OK, but he got super complain-y when he was put in uncomfortable situations, and his "relationship" with Renee was simultaneously boring and annoying.

Melrose Bickerstaff, Cycle 7
Although Melrose did well in the competition, she wasn't very well-liked by her fellow contestants. She was pretty annoying for the audience too.

Chantal Jones, Cycle 9
While Chantal did well in the competition — she was only in the bottom two twice — Saleisha was the cycle's obvious winner, and the runner-up was ultimately forgettable.

Chelsey Hersley, Cycle 15
Chelsey probably would've done better in any other cycle, but no other contestants had a chance in Cycle 15 - Ann was the clear winner from the beginning.
