Which 4th Gen GG is the most popular after StayC?

What I mean by the title is that I suppose most of us can somewhat agree that the Big4 groups (NJS/aespa/LSFM/ITZY/NMIXX?) + IVE + (G)I-DLE are bigger than StayC be it in Korea or Internationally. Also, for the sake of comparison we are excluding Kep1er since they are a temporary group. Not including Loona too since .... you know

Which group (after excluding those mentioned above), is the next in line in terms of popularity after StayC? Everglow? Billlie? Weeekly? Some other group that I missed?

Edit: fromis_9 too?

Quote from sveznalica

Everglow is close to disbandment I fear so we won't count them, Weekly has awful management so that leaves us with Billlie, they are definitely on a rise and I was surprised when I saw their sales.

Of course there is still big gap between them and StayC!

Everglow might be preparing for a comeback though. Yiren is back and Sihyeon hinted at a comeback
