Looking at the remaining women:
Amy - Definitely has the right "look" and demeanor. Because of her poised, professional, and classy look, people have dubbed her as the best of the women. I do not agree. What have we seen from Amy so far? Every clip I see of her involves trying to manipulate men for material gain (i.e., her behavior in the lemonade task, her behavior in the Shooter Girls task, her behavior with the transportation task-she actually had the nerve to try to get men to pay $50.00 for a ride up the street. Even Katrina, a woman who admits to using her looks for gains, thought Amy was going to far!). Nevertheless, Amy is currently the strongest because if you can get so many people to believe that you are strong, then that's really all that matters in this world.
Katrina - Definitely is a hard worker. It takes hard work to graduate with a perfect GPA, and achieve what she has at so young an age. However, Katrina still has a lot of growing up to do, and if she were to gain 75 pounds tomorrow, I have no doubt that her career would fall to pieces because she relies heavily on her appearance. There is absolutely nothing wrong with using what you've got. If it works, and men/women respond positively to it (as most of us do according to some studies), then by all means, do it! But again, what happens when the princess' looks fade? Will the only thing left be a bitter, spoiled brat? Also, she fell apart when Troy outwitted her in the apartment renovation task. Her reaction was childish, at best.
Heidi - Tough cookie, but it seemed as though that was all she was. Everyone likes someone who is down to earth, etc. but she just came across as very rough around the edges. She is more of a hustler, hard worker, who gets by from acting and not thinking. I didn't notice any creativity coming from her. For the record though, her personality is very similar to that of most men. Although the fact that she is a woman puts her at a disadvantage.
Ereka - I saw absolutely nothing redeeming about Ereka on the show. She was hot tempered, and, like many women, let her emotions control her actions. In many cases, her emotion-based decisions trumped logic and reason, which eventually led to her demise.
Krista - Too much of a crybaby. Would NEVER last in the cutthroat business world.
Jessie - I didn't notice anything particularly great about her. She only came across as an inexperienced backstabber, with a highly annoying voice.
Tammy - Seems very strong, but she didn't know how to "play the game." She was too results driven and ended up making a lot of inappropriate and insensitive comments. I think if Tammy could have toned down the comments and, instead, took on the role of the strong, silent type (sort of like Kwame), she could have gone very far in the game.
Omarosa - Could not get along with the other women, for whatever reasons. She was frequently placed in the situation of selling or marketing something she didn't agree with, and she did the job beautifully. Despite the overwhelming hatred of the other competitors towards her, she did continue to put forth the effort to interact with them. I really do feel that if Omarosa had been more under the radar, and acted super-friendly with the other houseguests, she could have won the whole thing. Its not as if she is not capable of being friendly, she just chose not to be, and in the end, that destroyed her.
