Mamamoo is known for all of that. Purple Kiss from their company is also very good but I haven't watched variety of them yet.
I just got into Dreamcatcher today so I only know music and talent but they get both of those. I still need to see video of their personality before I can answer that though.
Other suggestions I'm familiar with that could fit your requirements: Twice, SNSD, (G)I-DLE, Red Velvet, Viviz (Gfriend), EXID
Thank you very much for all the suggestions.
From what I know about Dreamcatcher fandom, is that they have a lot of fun there. And I don't think they really have fanwars?
Mamamoo is a great talented group. I followed them quite a bit, but drifted away a bit when they continued to do so much solo work instead of group work.
Is EXID still active?
