In my opinion, Gaga lacks in various departments and therefore she is very draggable. It's very hard to compensate some of her flaws with better qualities, because to me, her list of flaws endless.
Britney, Christina, Katy, Gaga, Justin Bieber. It's hard to choose one
For Britney it's very hard though. Although her career hasn't been anything special the last decade, the first few years of her career were extraordinary. She's extremely successful.
