Billboard Female Artists Of 2004, and 2007:

2004: Britney - Not #1
2007: Fergie - Was #1

Toxic is more iconic than any of the singles released from The Dutchess and along with the album sales and the tour its In the zone by a landslide

So is it true that In The Zone charted better than The Dutchess,had a better Metacritic score,sold more..
but Fergie s album had more number 1 hits on it?

Yes, we all know that you hate Britney.

The era with bigger impact: In the Zone

ITZ obvs

Album sales: In the Zone
Single sales: The Dutchess
Critical acclaim: In the Zone
Touring: In the Zone

Toxic is more iconic than any single from The Dutchess. I absolutely love both but ITZ wins.

The Dutchess was bigger, singles wise, no doubt. Toxic was big, but Fergie had 4 songs that were bigger than MATM and Everytime. I have no idea about album sales though.

ITZ is the better album though

The Dutchess obviously

In The Zone

The Dutchess obviously. The other album was a flop at the time.

ITZ

The Dutchess definitely.

ITZ. Fergie was a singles artist and none of her singles stood the test of time the way Britney's did.

The dutchess. Toxic is not anywhere close to being as iconic as fergalicious

The Duchess.

Fergie by far

In the Zone obv

The Duchess obviously.... I just love that album

'Toxic' alone is bigger than The Dutchess.
