The competition between gg is always more fierce than bg. For bg, it's always easy to determine who actually on the top. But with gg, it's always hard to see who actually the number one. People will still debating whether it's Snsd or 2Ne1, it's Bp or Twice and now with the new gen which gg will be the winner in the end. We have Itzy, G-Idle, Aespa, Ive, Nmixx, Lesserafim, Newjeans and ygngg.
I think because gg served more good music that it is harder for gp to pick which group doing better.
