Overall Ranking

1. Girls' Generation (Jessica)

2. 2NE1 (Minzy)

The biggest difference between boy and girl groups is that girl groups often face greater public scrutiny after a member leaves, whereas boy groups tend to rely more on dedicated fandoms that help them survive lineup changes. Nevertheless, groups like SNSD, I-DLE, and LE SSERAFIM prove that a girl group can overcome even a highly publicized member loss and continue to thrive.
