Let's say that they were at their ultimate peak in performing, popularity, and music. Who would dominate effortlessly, and who would be flopping hard? Let's say this all happened in a good music market (with sales like in the year 2000).

Ciara!

Lady Gaga.

Incorrect

KatY!

Xtina.

Christina tbh.

There's only one answer girls

She basic now, but none of the other girls have **** on Britney at her peak whether it's performing, popularity, or sales.

Britney any other answer is laughable. She was a phenomenon that hasn't been seen since Michael.

Britney. Can dance, sing and write.

It would be a shared top between Britney and Gaga.

All Gaga can do is sing.

BRITNEY None of the other girls even come close sorry.

Gaga writes her own songs and sings live....unlike some other popstar.
