no

obviously

No

Yes.

Yes

One of, we have Adele too

Who else is in her generation?

And Katy can do/does all those things in the OP too, no?

Rihanna, Beyonce, Christina Aguilera, Kesha...

Yes, Katy obviously can do it all, that's because she's also very talented, but I think we all know that if we rate Gaga's vocal 8/10, then Katy's is like 6,5/10. So I'd say Gaga is more talented, but it's not like Katy isn't talented.

It's just Gaga, Katy Perry, and Adele in their generation.

Katy Perry is the most talented out of the three.
