I think Taylor has been more consistent, sure Taylor won't have an era as big as The Fame WW but she has longevity and consistency whereas Gaga doesn't

US: Taylor
WW: GaGa

Taylor. This isn't even really arguable. It's notable that they're both in their own lane, of course, but in raw numbers, Taylor wins by a lot, actually.

Taylor easily. (US and WW)

Taylor Swift

Taylor. Voted for Meghan tho.

Lady Gaga sold 18m albums outside of the us
Taylor Swift sold 8m albums outside of the us.

I'm sure GaGa sold more singles outside of the US then Taylor
Touring GaGa crossed the 500m mark, Idk about Taylor

Taylor is bigger in the US but not WW.

But Taylor sold more albums.

Therefore, she is bigger in the world because more people bought her music.

.

Taylor is probably the last real popstar

Taylor
Consistency is King

US Taylor but outside the US it's GaGa

GaGa also sold more records and grossed more in touring.

Taylor has sold more albums and will have sold more singles by the end of this era. She will also surpass Gaga in touring. She has already passed Gaga in streaming.

Taylor is undeniably the bigger global act.

Taylor has proven herself as a lasting force while Gaga kind of came and went and will probably stay gone.

Taylor

Taylor is bigger WW and in the U.S.

Plus is not just about sales, it's about impact too.

Taylor Swift is barely known here in latin america, just by her fans. Meanwhile Gaga is known even by the GP.

You go in every thread about GaGa and keep saying the same thing over and over again, which is hilarious since you go on and on in other threads trying to prove how other artists are "relevant" and "bigger" when GaGa demolish them easily.
