who is currently the biggest group in SM entertaiment ?

Because I can't afford to be on another hit list I'll say Red Velvet.

dreams?

Still Aespa

Idk if Aespa was ever less popular than RV

NCT.

EN SEA TEA

Aespa?

End Si Tee

N city, for BG

Aespa, for GG imo

RV is consistent, unless they release a good VELVET SONG (my wish) and an upgraded choreo

Nct Dream

Aespa

from those 3, nct.

Maybe nct

i know nothing about nct but between aespa and rv, i'd say it's the former

aespa have the physical sales and some good streaming performances so them.

NCT

SNSD
