Lulu!!! oh my god, no competition! for a start she was in a far more superior game, and she had a more defined personality and i LOVED her voice. her character design was really cool and intricate too, and she just more gentle and personal, as well as tough.
Paine just reminded me of some spoilt teenage brat trying to be a rebel, kind of like Avril Lavine *shudders*. She was so flat and had a weird, ratty look about her. THAT SAID, some of her sarcastic comments raised a smile, but it always seemed so out of character when she took part in the Charlies Angels pose etc. with Yuna and Rikku. She just bugged me.
