Shows like Dancing With The Stars, NB and JDJ have a very specific goal, take a celebrity that is a non-dancer and see if you can turn him/her into a dancer. In the states this year, Helio won over Mel B because he was a total non-dancer who turned into an amazing dancer, whereas Mel B, having performed with the Spice Girls, was already somewhat of a dancer. The same thing happened on JDJ this year (and last), Prachi, a total non-dancer won over Sandhiya, someone who had some dance experience prior to coming on the show. On NB, the theory is a little bit different in that one of the two in each couple is a dancer while the other is not, but in the end, the goal is the same. So, it would seem right then, for Sanjeeda-Aamir to win over Rakhi-Abhisheik since Aamir is a total non-dancer who turned into a great dancer, while both Rakhi and Abhisheik were good dancers prior to joining the show.
No offense, just my thinking...
