This was actually a difficult piece to write. Outside of an obvious top 3-4 groups, the rest of the rankings were murky for a long time. I tried using some "sophisticated algorithms" to help look at each group from a music and activity perspective but even then I still changed the final list like five times at least. In any case, these are the best girl groups right now based on their lineup, recent showings, and where they're headed, with some legacy points tacked on. Also a reminder that "new releases" covers anything that was released since the last ranking, and that even goes for groups that are appearing on the list for the first time.
Honorable Mention: Sonamoo
* New Releases: I (Knew It)
After flailing around in concept inconsistency Sonamoo have appeared to settle down in a zone. "Friday Night" and "I (Knew It)" are solid tracks that deviated from the much less enjoyable bubblegum dance pop they had throughout 2016 and early 2017. Currently the group is watching Euijin take center stage with UNI.T which could be a turning point in their group's career path. This will either give them a jolt of life or be the beginning of the end. Considering their label is TS Entertainment, I'm keeping them on my radar but not trusting their label until they prove otherwise.
Honorable Mention: CLC
* New Releases: Black Dress
Similar to Sonamoo, I can't trust CLC because of Cube. They're already planning another girl group despite CLC not yet having a stable foothold in the industry yet. "Black Dress" was a great track but last time we were treated to a tougher, girl crush concept they immediately heel turned into "Where Are You?" which was the exact opposite. With both label and genre uncertainty, I'll place them in the Honorable Mentions for now. Fun fact: three out of five groups that started in Honorable Mentions went on to join the official list so maybe there's hope for them yet (and Sonamoo).
#10. Black Pink (-6)
* New Releases: N/A
Live footage of Yang Hyunsuk working on Black Pink. Seriously, what a joke. They are the least active high-profile girl group and it's not even close. Even 2NE1 out the gate was not this pathetic discography-wise. What's that? Black Pink has an album coming up soon? Nice! Oh, it's merely their prior five songs in Japanese. Fuck off outta here YG, this is some bullshit. The only reason they're not in Honorable Mentions (or off the list entirely) is that their worst song is still better than CLC and Sonamoo's best song.
