I agree that blinks exaggerate how much BP is ahead of Twice. I mean some of them think they are at the same level as BTS, lol.
But for sure, BP has moved ahead of Twice since 2020.
There usually is never a group that totally dominates, even during SNSD reign, Kara was doing well if not better in Japan, 2NE1 had better numbers in the west. T-ara was doing well in China. Sistar could dominate the summers.
So BP vs Twice is as you say not a total domination.
But over all, BP has been more consistent with their hits. Their biggest miss was ice cream, and that was an English song that charted #8 on Gaon.
BP are the queens of YouTube.
BP gets higher peaks with their streams.
BP comebacks are global phenomenons.
BP are some of the best social media influencers (this helps sell music, not just clothes).
What Twice has over BP, is Japan and that Twice makes a lot of good music, they do not need to rest for 2 years while they go to fashion shows all over the world, Twice just puts out music for their fans. Blinks can only dream of having half of Twice discography.
