Faster to reach 1M sales: Red Velvet or a 4th gen gg?

Right now Red Velvet last album did more than 500K, higher than all 4th gen ggs. But Ive/Lesserafim/Nmixx/Aespa are already pulling 400K and can grow quick. Who do you think will become a million seller faster: Red Velvet or a 4th gen gg?

aespa will sell 1m before them, idk about other 4th gen ggs though

RV aren't on a trajectory at all to reach 1m.

Depends on who will have a comeback first, and how many this year, I guess.

At this moment Blackpink are the only gg who have surpassed 1M album sales, and they did that 1.5 year ago, no telling how many they'd sell now. Not even TWICE have surpassed that threshold yet.
