I think ppl forgot how huge Xtina was during her debut. Brit was a pop culture icon and yes she was everywhere. Xtina was also the it girl too, ppl lump her with Britney but she was Brit's peer during the debut. Xtina had 3 number 1s from her first album (GIAB, WAGW, COOB) while Brit only had a number 1 with baby one more time. Xtina had longevity with her debut album where it lasted from 99-01, then xtina hit hard with lady marmalade. Both ladies were everywhere during their eras. Both dominated 98-004ish, with their respective albums. Not to mention Xtina had a huge era and impact in Latin America with Mi Reflejo and then stripped worldwide. Brit was always a singles girlie and her music catered to the pop ears, while xtina was an album girlie where the album had longevity, where her music was more critically acclaimed.
