IVE have been charting so well on kchart. After Like peaked over 600k uls which not much singer can reached that number on Melon nowaday. After Like also have insane Longevity. It have beaten some song that released later.
Love Dive winning the soty, reaching raks after few months of release is pretty insane.
Lesserafim charting is very good as well. Fearless peaked similar with eleven and Antifragile have similar number with Love Dive as well. Both of their song have strong longevity, but IVE's longevity is better. After Like is released before Antifragile, but After Like almost surpass them and Love Dive is going to surpass both of them lol.
Aespa's recent charting isn't as impressive compare to the other two. However, it would be stupid to say they cannot beat both of them. Next Level is after Black Memba where it didn't do great.
Any of these groups can beat each other and I don't think there would be clear winner before we can actually see their charting.
International Chart
1. Lesserafim

3. Aespa
Leserafim's Antifragile is probably one of the favourite song by the international fans. They have great longevity and high peaks as well.
IVE's AfterLike peaked at 23 in Spotify Global with around 2.3M stream. However, the song's longevity isn't as great as Love Dive whom have lower peaked stream.
Aespa only went for 1 day on Spotify Global. It just hard to see how they can beat them in global charting.

3 of them are going for million sales for sure. However, based on previous comeback, I think this is the only visible ranking at the moment. However, I'm not surprised any of these 3 topped the sales.
