After watching the 2 episodes that came out it goes as follows:
Jenni
Kortnee
Nikki(Hoopz)
Erika
Meagan
And honestly after looking at the 2 episodes, Nikki, Erika, and Kortnee are interchangeable as far as who looks best, but Jenni is clearly the best looking and Meagan, while attractive, is the least best looking.
And after saying all that-- judging by their personalities out of all the sisters, I'd choose Erika (goofy, silly) and looks, Kortnee
