The one thing that is unique and different on afreeca compared to both twitch Korea and chzzk is how social streamers are with each other. They do those collab streams with other streamers and join different groups. Haruzzxng and Woojung both joined a group after switching to Afreeca. Froggy did too, but she had to drop out due to health issues, but she still constantly streams with others. Youchi also streamed with Namsoon and I guess may join Sooni group sooner or later.
If woo wants to stream with others then afreeca is the best choice over Chzzk. Also, if money is a priority, and I think it is for Woo (Hakuna exclusive contract), Afreeca >>> Chzzk. Someone posted on the naver forum that the top earner on Chzzk wouldn't even crack the top 50 highest earner on afreeca right now.
