Brandy: The “alt-R&B” pioneer with a focus on harmony and texture. Her image was the “good girl” with a sophisticated, moody sound.
Monica: The “soul-belter” with a powerful, traditional R&B voice. Her image was a bit more “street-smart” and her vocals were more direct and forceful.
Comparison: Their rivalry defined the 90s. Brandy is for the fans of “vocal production,” while Monica is for the fans of “raw soul.” Their hit “The Boy Is Mine” remains the greatest “diva duet” in history.
