Its way too difficult to compare between 2nd gen and 3rd gen ggs.
But I dont think its a stretch to say that 2nd gen ggs did way better digitally in korea than 3rd gen ones. Even 4th gen ggs seem to do better and they have just started. Outside of Blackpink/Twice nobody is consistently really big or get super big hits in korea in any big period of time for 3rd gen ggs.
So I wouldnt be surprised if the list is dominated by 2nd gen + NewJeans or Ive + Blackpink and Twice. The only issue with 4th gen is that they dont have the number of songs under their belt but they already have at least 2 way bigger hits than MMM/RV (3rd/4th best performing 3rd gen gg) ever had
