B'Day is her best album and I won't hear another word about it. It has the perfect uptempos, it has the perfect ballad (Resentment) & it has the perfect midtempos. She was sexy af during the era, she was performing at the height of her talent (at the time), & she just slayed everything.
But it's not question IASF was the best thing for her career, despite how lackluster the album was.
Rated R is one of the best pop albums of all-time. Everything on the album (except Stupid In Love) slays. Beyonce, Gags and the other pop girls could neva.
