Britney was massive in early 2000s.

then Lady Gaga came... She was like a phenomenon when she came out. It was frenzy in her peak. She had the biggest buzz/entry in music after Britney.

But who had the biggest peak?

Britney and her longevity >

Britney

GaGa by very far

http://www.billboard.com/charts/grea...ard-200-albums

#12: Lady Gaga - The Fame
N/A in the top 40: Any Britney album

And that is Britney's biggest market by far (her albums charted very poorly outside North America) while GaGa was even bigger outside the US

Britney double diamond selling Spears.

Obviously Britney

#1 albums/singles (3 decades [US & WW]). Daily coverage without propaganda just purely on a recognizable, influential and impactful legacy. Iconic videos, songs, performances. 100M albums shipped 100M singles sold. Top 10 ranking all time best selling female artist. 2 diamond albums. Top 3 female in WW album/single sales over the past 20 yrs Which is difficult to get, not everyone has that.

Nobody since Britney peaked higher than Britney

I think their peaks were about even

Okay

Britney! If you vote for Gaga I assume you are a 13 year old

This thread again
Britney's, it had impact that gave her longevity.

Britney.

Gaga, at her peak she had the biggest album of the year (2009, 2010)

Britney was being outsold by the likes of Eminem, Santana, Backstreet Boys, etc

I agree that Britney outlasted Gaga though

Britney : 2 diamond albums
Gaga : 2 diamond singles

it's even!

Gaga singles were not certified diamond during her peak. lol

Britney

Britney.

Britney. I honestly believe no other pop star will ever be as successful or impactful after the era of Britney.
