S Club 7
S Club 7 are better than other teen-oriented, dancing popsters such as Spice Girls or Backstreet Boys for two reasons. First, there are seven of them, and that beats four Spice Girls or five Backstreet Boys hands down -- it's basic arithmetic. Secondly, S Club 7 have both guys and girls in the group, which is better than just guys or just girls. Other than that, it's all the same, really.
