Personally, I'd have to go with PCD for obvious reason. But stanning aside, Destiny's Child. Amazing catalogue, incredible performances, great impact. I know Spice Girls are a phenomenon but I just never clicked with that group.
I guess I like to be entertained when it comes to the songs and the live performances and only DC and PCD gave AMAZING live performances. They really knew how to get the crowed going.
But DC>>PCD. Even Nicole said they were lucky that DC wasn't around at the time PCD skyrocketed to the top because they could never touch them.
