Lol as if it's any competition.
PCD all the way. They were the global ones for a reason.
More and better hits, and there music undoubtedly aged better. Buttons is over 10 years old and still sounds fresh. GA could never.
Girls Aloud remain the best girl group of all time and their music did things that PCD could never pull off. Being local or having less impact doesn't matter in this case. GA's debut single alone ***** on PCD's discography.
