Every single time I see 4th gen girl groups being discussed, people always mention how only a few members are popular in a certain group. For example, you might have already seen something along the lines of this but:
"The only relevant person in gidle is soyeon."
"Ive is being carried by yujin and wonyoung."
"How is stayc popular when most people cant even name all the stayc members?"
Etc.
However I don't think theres a single 4th gen girl group where all the members are popular.
Popular members per Group:
gidle: soyeon and yuqi with shuhua making a few waves
stayc: yoon, with sieun making a few waves
ive: wonyoung, yujin, with leeseo making a few waves
nmixx: sullyoon, jinni, with lily and haewon making a few waves
les serafim: sakura, chaewon, and garam except garams popularity is just... yk
billie: literally only tsuki, maybe sua if you're being nice
everglow: yiren, Mia with shihyeon and Aisha making a few waves
Kepler: yujin, babihiyih, with xaioting, mashiro, and chaehyun making a few waves
I think at this point the only 4 girl groups where nonfans might be able to name all the members is Itzy, Gidle, Ive, and Aespa but even then, that's just naming. That doesnt mean all the members are popular and it's kind of dumb to try to out down a certain group because they're only popular because of a certain member or two when that's applicable to all the 4th gen eggs.
