Mandana is stronger because she is all by herself in a house without any acquaintances. On top of that she is doing all this using a language she is not fluent in. Kishwar on other hand has unconditional support of Prince and Suyash along with support of Rimmi and some others. If Kishwar was all alone from day 1iin the house then we would have had better match up between both but having 2-3 housemates constantly supporting you, makes a huge difference in confidence and game.
