Nijisanji, right now, is a good company to join to get started with Vtubing, and it's worth staying with them if you are very successful there already.
If you already have experience, or if you have been there long enough to learn how it works but you aren't getting any traction, the smart move is not to bother with it; in those cases, many other corpos have better arrangements, or going indie could easily work out better.
This wasn't always the case, but it is very clear that something behind the scenes has changed drastically at the company, relatively recently.
