I'd say that Nynaeve can be more annoying than Faile at times, but yes, I like both the characters myself. Nynaeve certainly had her annoying moments, but fighting Moghedien, helping Rand with the Cleansing, and raising the Golden Crane for Lan more than make up for her annoyance factors. Plus she's good for comic relief at times, like telling Elayne that only ninnies think they can get anywhere with threats. I agree that she kind of lost some of what made her good as Egwene became more important.

Faile is sometimes immature, but she's also the youngest of the females. Yet, she's still more mature and level-headed then some of them at times. She's also very much devoted to Perrin, and does what she can to help him, even if it means going behind his back.

I find Elayne and Egwene to be more annoying then these two. Egwene has improved a little bit, but Elayne really hasn't done anything to make me like her. Even her work on ter'angreal is overshadowed by everything else that I don't like.
