Harribel couldn't kill her opponents, and was quickly killed by Aizen and played off as worthless. (I don't find her to be such, she just had a very bad match-up that consists of constant Elemental Rock Paper Scissors).

Nelliel, by all means, was awesome, but Kubo then decided to screw her over by making her revert to her child form, ultimately get crushed, and they all had to be saved by Zaraki. Besides, she had to get into her release to cause any significant damage to Nnoitra. What if Nnoitra had released? Nelliel would have been punted aside like all the other females in Bleach that Kubo doesn't let do anything >_< Trust me, I am ALL for action girls, my fanfiction has plenty and it's a reason I love Fairy Tail, I just wish Kubo would use them more
