I dislike Swift and Perry with a passion.

For voice: GaGa; for lyrics: Taylor Swift.

I think she's a better singer but Lady Gaga's songs are a lot more addictive and she's also better and presenting and selling herself than Taylor. She's kind of like the new Madonna.
As for Katy Perry, I like a few of her songs but I find that she tends to sing out of her vocal range and it doesn't sound good. She needs to become aware of her limitations.

Gaga. I used to not like her, but now I'm growing more attached to her for some odd reason. XD

none. none of them. :\

She's way better

dont like the other two.

katy perry no chance at all

Katy Perry Has A Dry Voice,Taylor Swift Is Not The Kind of Music I Like,Gaga I LOVE HER!

I hate Lady Gaga because she dresses like a stripper and Katy Perry because of California Gurls. Taylor rocks, I enjoy her music :)

I listen to all three.

Sometimes I feel like a plastic bag...

Swift and Perry don't stand a chance against Gaga when it comes to sheer vocal talent.
