This talk about whether Pomu would consider trying for Vshojo vs Hololive.. it sounds like it'll come down to if she is truly in retirement easy-mode with former niji friends or does she still have idol dreams and wants to be on the biggest possible concert stages for vtubers. I never watched her ever so I'll lean on her fans to chime in on this. Is Pomu going to just stream games and do lazy reactions to "Every 40k Faction explained part III" by Bricky and whatever Twitch drama is going on atm with Asmongold, Destiny and Pokimane.
Hololive is the one with the brand new studio and guaranteed multiple in-person concerts a year + much more online only performances and events, and being on the same stage as vtuber legends like Suisei, Sora, etc in front of 6k+ live audience. The downside is still having to deal with JP bullshit, much less talent freedom, and probably having to wait half a year if not more to debut (if accepted). Again, it'll depend on if she wants to still do the true idol gig thing. Hololive is on another level when it comes to the idol thing, no one else is close.
