If I had to list Big4 companies based on the success of their acitive groups (as of 2021) and how much income they made, it would look like:
Enhypen sales were incredible, Seventeen doing great in japan + good sales, Bts making buzz
Rosè halfmillionseller +global success, The Show revenue, Treasure japan debut + sales
Several shinee cbs, superjunior cb, NCT dream preorder
