Their career is far from perfect and it went completely off the rails since like 2020 but somehow other ggs are even worse. NJ had a great shot but for the reasons they are not responsible for (I mean their parent company CEO actively hates and sabotages them) they kinda lost the chance the way I see it.
BP chose to go their own way even though they honestly did have a shot at winning against Twice in a longevity battle, since they were still charting, their musical image was great. But comparing 7 years to 7 years Idk how can some blinks still be that delulu and think BP has achieved more
SNSD....well their individual success and variety of it, aka Yoona acting, Taeyeon still slaying charts remains the greatest. However as a group Twice has more achievements and lets be honest, SNSD's music hasn't aged well and they weren't really ever digimons, got outcharted by most rivals.
And I am not even saying this as a Once, yall already renounced me from the fandom for hating too much and I didn't even object to that. So I am just saying how it really is without bias.
