Overall what puts Bey over Janet, Jlo, Madonna, Gaga, Early 00's Britney, P!nk, etc. as a performer is she is more all-around than any other female performer ever. You have the exceptional dancers who are mediocre singers (Janet, Ciara, Jlo, Britney). You have the exceptional singers who don't dance (Whitney, Mariah, Celine, Aretha). And you have the visual artists who are okay dancers OR singers (Madonna, Gaga, P!nk). Beyoncè is one of the top tier vocalists in music today and she has proved multiple times that she can perform articulate dance moves and choreography all while doing it at the same time. This is what puts her before any other female tbh.
