Display MoreGirl's day was just below Apink, neither group was top tier.
Both groups had some top 10 hits, but Apink had way more sales (bigger fan base).
Girls day did have a #1 song with Darling, Apink never got a #1 song.
Both groups had a couple #2 songs.
Girls Day had a string of hits even if most of them didn't go to #1. Something was the most successful GG song from 2014, Hyeri was a huge it girl, most of the members had individual popularity etc. They were the biggest girl group in 2014 imo, only lacking in physical sales
Apink won the longevity game but Girls'Day wins based on peak easily
