The Fame Monster will probably always be her best album as a whole, but that's because it was very short; The Fame will always remain 3/4 fillers with some great singles. Born This Way and ARTPOP are basically equally great (still can't decide so soon, certainly ARTPOP hasn't got a song as bad as Highway Unicorn or Bad Kids or the bonus tracks but also it hasn't got a song as good as The Edge Of Glory).
Oh, and her vocals on ARTPOP are her best ever
