Bey's best selling album sold 10M and Taylor's best selling album also sold 10M.I think their peaks are very close.That's why I am doing this comparison.

So both have huge careers and longetivity but which one has the bigger peak?

Consider everything from star power to touring.

taylor, sadly

Taylor, Beyonce has never been number 1. She's always playing second fiddle.

Beyonce easily. What is Taylor outside of album sales?
Both Beyoncé peaks are at least 2-3x the size of Taylor's.

I voted for Bey,too because she is more global imo

Bey

This. Both woman are very talented and successful tho.

Taylor is also bigger globally

When taking into account SPS and touring: Taylor.

The 1989 era will be bigger than any Beyonce era when the tour is over, and the album will have outsold every Beyonce album in the end.

lol

With Destiny's Child: Beyoncé
Without Destiny's Child: Beyoncé

But Beyonce sold more outside of USA with DIL?

BEYONCÉ is not only not her peak, but one smash single doesn't make her more global. 1989 slaughtered STed's worldwide sales, Taylor had a bigger tour, and 1989 had overall way more successful singles globally than any Bey era.

hard to answer

Taylor's been the biggest artist in the biggest charts in the world in 2009, and 2013 while Bey's never done that at all once, let alone twice like Tay.

I don't mean to sound blunt, but, like, who cares? Raw total sales are important; where purchases were made really means very little. If 1989 sells more, it sells more, US or otherwise.

Beyonce

Taylor will end up selling very close to 10M in this age of widespread online piracy and dwindling album sales. She wins.

Not more than I'm Sasha Fierce.

Since this thread is about everything including globalness.I do

1989 is Taylor's peak, not Fearless. Fearless was global for a country era though, so if we believed Fearless to be Taylor's peak, she still wins.

Taylor. Her 1+ million openers speak for themselves
