This is not meant as shade to LSF; I'm just curious who are the girl groups who could've "just done their jobs" if in the same situation as LSF.
Based on what I've observed and heard in person, my list is:
(G)I-DLE
If I include third generation, I'd throw in Mamamoo, Red Velvet, GFriend (Yuju would hard carry the weaker vocalists) and arguably Lovelyz.
