Both Eras are very alike in many ways both albums debuted in the 250K range both lead singles debuted within the top 5 and their second singles peaked within the top 20 and both girls had erratic behaviors which made them media targets. At the end of Blackout run it had the same sales as ArtPop, within 8 years Blackout reached the 1 million mark in the U.S. but which Era was more successful?

Blackout sold more and actually reached platinum.

Blackout

Blackout, certainly.

Still regarded as one of the greatest pop albums of the aughts, plus the iconicism of the '07 VMA performance, plus "Piece of Me" winning VOTY...

ARTPOP.

Applause > Gimme More
DWUW > Piece Of Me

Both albums were successful (just not as much as their previous work) and - amazing especially ARTPOP - tho

Blackout of course. It's also the better album by far.

In what world?

Blackout, why is this even a question?

Obviously the one that made IFPI's global top 10 year-end list

Mess @ Blackout not even making the top 30 of its year.

girl.......

I prefer Blackout, sorry Gaga

Because their sales were identical at the end of their era's

Blackout won a VMA. Nothing from the AP era was even nominated. It also sold more.

Duh. In our world

Gimme More sold 3,1M WW in 8 years. Applause sold 4,7M WW in 2 years.
Do What U Want sold less than Piece Of Me, I didn't know that, but DWUW didn't have a video.

Both albums sold 2,500,000 but sales now are way LOWER than they were 8 years ago, so ARTPOP is the only good answer.

It's Britney Bitch alone slays all of the ARTPOP era

ARTPOP is at 1.9-2m sis.....

How tho? Applause sold way more than GM, that's a fact

It sold more because 2007 album sales were twice as high as 2013's

One album was in the top 10 best-selling albums of its year, the other didn't even make the top 30. Anyone objective would conclude that the former is more successful.
