Don't know them personally so can't tell who is fake. They all are playing and trying to win in a SHOW so by that logic they all are fake else none. If you ask about who i like betwen these two then i will pick Sana. Reason Urvashi has arrogance in her more than Sana. I do see glimpse of arrogance in Urvasii when she gets in the arguments and stretches it and then makes fun of the person behind their back. She needs to have the last word and has to get personal to bring them down and ofcourse behind their back.
