Who will be the best selling gg of all time?

in kpop, it will be twice for a long time since they release quite a lot, aespa or other 4th gen ggs may catch up, aespa has a chance of surpassing them too. Won't say bp though because they hardly ever release, they're 6 years old group but only has 2 minis and 1 'full' album as of yet
