How is this a question? Beyonce's debut was 2 years before Britney & her career is currently doing better.

This poll has been done so many times. It's pretty obvious who has maintained their level of success the best.

Their respective careers arent over yet. For all we know, Britneys will be like Chers, and Beys like Janets

The one who sold 800K In 3 days In December

Britney by far.

Any recent receipts?

Nnnnn; inb4 the mess.

But clearly it's Bey

Britney. 2 whole decades of slayage with little to no effort.

wishful thinking
care to elaborate?

Britney had a way more successful SOLO career ... If Beyonce was a solo act from the beginning, she wouldn't be this famous now ... Britney's a LEGEND, ICON, she's BRITNEY ****ING SPEARS ... while Beyonce is a successful singer ...

Beyoncé is like Queen Elisabeth. She remains unbothered on top while the it girls princesses come and go.

Lets see how Beyonce, ha 6th album does most of my bey stan friends irl tell me after the initial hype, they deleted the Beyonce album cuz its lacklustre

^which is oddly how my former Gaga stan friends felt about BTW

I feel bad for Brit

Bey is still rolling, the other well...isn't.

Beyonce

In before the mess and delusional posts to come.

The answer is obvious

cute post but u didn't answer the question

1998-2014=16 years =/=2 decades
And Britney hasn't exactly slayed all that time either
We don't live in this parallel universe you're viewing in your crystal ball, so that's kind of irrelevant.
But anyways, the OP is asking which one has had more longevity, which you failed to answer with validity.
