Anyways my vote goes to Xtina
The fact she has a huge career in the early 2000 even tho she was in in Britneys shadow should alone be a reason she's peaked better than Gaga considering she had to work harder to be in completion with Britney for all those years
Gaga in 2008/2009 didn't really have that much completion that was life threatening to her career like Xtina did and still I can't deny Gagas impact during those times as she was huge because she was so different compared to pop stars like Xtina, Britney, Pink and Beyoncé the only time Gaga started having real trouble was Katy Perry and her Teenage Dream era when it kicked in and since then Katy has always seemed to out peak and outsell Gaga on the charts
Now In 2014 Gaga is doing terribly i was personally shocked at her decline is happening so fast I thought shed have at least a good old 5/6 years before she started to fall but the fact it's happening only with her 3rd album proves the "fantasy of Gaga" is fading and fast her album sales recently are poor compared to her others and the same with her single sales which is a cry for help in my opinion
Xtina even tho her latest albums have done poorly she's still manage to maintain a few 3x Platinum hits with other artists so to say she's completely irrelevant is hilarious, doesn't help the fact Xtina hadn't promoted properly since (B2B AKA Being all around the world) while Gaga has been all around the world with ARTPOP and it still is struggling to sell anything ATM
So yeah to sum it all up my vote goes to Xtina
