>>16828819In general, you can't go wrong with the group collabs. It is Holostars' main strength, so you can check out their special MC events like this one:
https://www.youtube.com/watch?v=wu0Et-co2BY or the xmas tree event. The two first AmongUs collabs or Golfit in particular are comedy gold.
I watch mainly Roberu, so I could recommend almost everything from him outside from gaming, especially the Bar Robel where he invites other vtuber for a 1-hour freestyle zatsudan, or the Hen no waku which are gorilla streams where he does stupid shit.
Since you asked for Oga, I liked his game creation streams, but unfortunately he barely does them anymore, most probably because of a previous stupid incident. His Megaman streams are also cool, he usually finishes them fast but retrogaming is oddly relaxing with him. He also sometimes does karaoke streams if SOUL singing is your jam. He also often does zatsus around the same hour after work, but as
>>16829565 said, omaesans are super horny, but they are also super chill outside from this. Finally, he has group collabs with FBK (FOXDEMON) or Aruran/Risu/Iofi (Kira Kira Family) that you can check out if you want some holos with it.
