Pink, obviously. Christina and the other girls....their careers are in the pits.

It's a tie between Pink & Christina.

I prefer Mya anyway.

All of them except Mya. It's not that she's not good, but she isn't as well known.

P!nk. She's still sh!tting while the other gorls didn't have as much as luck as her...

Pink, bar none. If Bionic were never released, I would maybe consider Christina.

P!nk

Of course Xtina!

P!nk

Pink has been more consistent than anyone of them. She had one bump in the road (Try This), but even that era wasn't like, for example, Bionic.

P!nk is ******** on everyone of those girls. She's bigger than all of them. She's one of the biggest stars worldwide now. She's achieved so much. I LOVE both Xtina and P!nk, but P!nk has had the better career.

P!nk.

I voted Pink coz she's the most consistent outta the four

Otherwise it would have been Christina (minus Bionic)

Pink has never reached big success like Christina

P!nk, followed by Christina

It's down to Pink or Christina.

Pink has never had the mega success of Christina's first two albums, but she's also never had the mega bump of Bionic either. I went with Pink, though I definitely wish it had been Christina. :-/

Obiously, P!nk

I am going with XTina based on general popularity, album sales, and awards garnered. Pink has definitely been more consistent, but continues to be underrated and less iconic than XTina.
