I think she's excellent and personally I feel shes a much better bassist than anyone they've ever had before she just looks like she can play if you know what I mean, D'arcy always looked like what she was playing was the edge of her ability (i.e. concentrating) and Auf De Maur as much as I love her and have seen her live and bought her solo album just doesn't have that presence and ability that I think Ginger has.
I don't know I mean it can't be purely her looks clouding my judgment because Pumpkins have always had hot bassists this one just seems better.
+1 on her singing as well, shes just great and again Pumpkins have benefited from her vocal ability.
