Pros: She is a great singer and is very talented and beautiful at times.
Cons: Her damn clown make-up, takes too long with albums, and she seems like a bitch sometimes.
Pros: Fantastic voice. I have to say one of the best vocals from the past decade.
Cons: Too much space in between her albums and there's always one or two album fillers. Poor single choices. She also lets opportunities slip through her fingers.
PROS: She has definite vocal talent. She's very professional and (Dirrrty, chola-browed, chap-wearing, Xtina stage aside) she has a fairly respectable image.
CONS: She does not know how to use her vocal talents in a mature way and constantly sounds like she's showboating and attempting to wow us when she doesn't need to. Has never seemed overly personable/likeable. Her career has no momentum; she releases music when she pleases which has provided ample opportunity for other girls to come in a usurp her throne.
Pros: Amazing voice and she's finally learning how to use it right. Her best songs are quite good. It's nice to see a pop tart doing something different and working with Sia, Ladytron, etc. for the new album.
Cons: Massive ego, she has said something bitchy about pretty much everyone in the industry. Her constant talk about how amazing her life is gets old. As good as her good songs are, her worst songs suck and she has a lot of them--inconsistent quality in her albums.
Pros -> Amazing voice, great singles, has control over her music, good mid-range belting, very creative
Cons -> Breaks between albums, overshadowed easily, strain in her higher-notes, filler on albums
