ARTPOP > BTW > TFM > TF.
BTW's highs are higher than TFM's highs (except for BR which is the best song out of both TFM + BTW), but BTW's lows are really bad and drag it down.
Her music has gotten better each time. I really think her issues are mainly to do with image and marketing, more superficial stuff. However, some of her single choices have definitely caused people to really not like her.
