All of them have good genin qualities but Temari is the best overall. Sakura is smart and good at chakra control, Ino knows how to use her mind transfer ability really well, Tenten is great at her weapon accuracy, Hinata is good with her families Bloodline limit (but not as good as Neji), the Sound girl ninja im not really sure on, but Temari's fan and her abilities she can use with it (and things she can do, like marking down where Shikamaru's shadow was) makes her the best female genin.
