wendy wouldnt be that low bc she was super hyped as a rookie and ppl argued over if she was the visual and abt her vocals skills.
also yeri would be more popular than giselle bc she got so much attention (and hate) for joining the group later on but she also had fans from smrookies
id also say that seulgi was more popular than joy and ningning at debut but the rest of it seems on point
Winter > Irene/Karina > Seulgi > Ningning> Wendy/Joy > Yeri > Giselle
Actually adding FX....Sulli/Krystal were around Seulgi at debut (blew up later but Latacha wasn't well received) I think Victoria was around Ningning to Joy, blew up 2-3 years after debut. Amber was around Yeri (TomBoy and unique) and I think Luna...was last.
Winter > Irene/Karina > Seulgi/Krystal > Sulli > Ningning > Victoria? > Wendy/Joy > Yeri > Amber > Giselle > Luna
wow props to Winter I only see SNSD Taeyeon, Yoona coming ahead of her in debut popularity.
