I unstanned BP after it became obvious they were a group in name only. I hung on for only Lisa towards the end. I am now neutral about Jisoo/Rose but get bad vibes from Jennie tbh (ive recently seen dozens of vids of Jennie looking utterly disinterested in front of Blinks who paid hundreds/thousands to see her perform).
I still check in on Twice from time to time.
The only other group ive ever stanned is Izone obviously. They will be my ult ride or die.
