Between the main four (no offense @ the bree lovers) , my vote switches everytime one of em posts a new sexy ass pic.
When Brooke finally shows her body and stops hiding behind her giant purse, she's the baddest. When India puts down the coke and gets back in the gym, she's the baddest, etc.
Crystal is the most consistent out of all of the others, as far as thirst traps. I'm not surprised she's winning.
