Based on generational metrics who was bigger f(x) or Itzy?

Both groups are similar in a lot of ways as they both followed label mates who were considered NGG.

They also both had 5 members and were more edgier and experimental compared to their big sisters who went with more girly girl sings and concepts.

Or better yet I'll put it this way. SNSD and Twice were aimed at guys while f(x) and Itzy were aimed at girls. Nuff said.

Success is interpreted different for each generation so of course Itzy has outsold f(x) by a lot. But different times call for different measures.

Yall already know I'm biased but I will say I don't think any member of Itzy reached Krystal and Sulli popularity. These two were huge in CFs and acting roles and top visual lists. But as far as group power I'd like to hear your case.
