The joke use to be "Beyonce as a whole (solo)

has yet to outsell Baby One More Time worldwide"

so now that Beyoncé has come within reach of those sales

with the release of BEYONCÉ and now that the MCWT

has outgrossed Britney's highest tour.

Is Beyoncé now deemed the more superior act?

That happened awhile ago. Brit will always have the memories of her time on top to remember though.
