Now, Holo has or had better average talent quality. The issue with Niji is it was too top-heavy. Pomu, Selen and to a much lesser degree Nina created the Niji collab mood and carried it until they just couldn't any more because instead of payoff for their efforts they got idiotic management decisions and free-coasting colleagues. When they left, only the chaff remained.
If you think about it, NijiEN didn't have a brand identity besides being the potential "Holo killer" and being less idol-y. It was entirely about a particular group of people, their specific interactions and inside memes.
I'm not gonna even talk about the males, it was a move that made the company lots of money but essentially undermined the girls' importance and cohesion of the fanbase.
Going back to the girl talents, they are a very disparate bunch, and without the Pomus and the Selens to glue them together, there's no reason for them to exist as a single entertainment unit.
For example, Rosemi better belongs in Holo or even VShojo (although Vshojo lacks a top-down identity, it's the specific friend group type of a unit just like early NijiEN used to be). Finana would fit Phase Connect. Enna has enough personality (rotten as it may be) to make it as a 3view indie with lots of effort. I don't think she's a great corpo fit anyways because she's bad in collabs.
tl;dr: there are two types of corpo units: 1. units made with a certain vision like Holo; 2. more organic units that are essentially "friend groups" like Vshojo and early NijiEN. Niji's mistakes were: pivoting to males and losing "friend group" centerpieces. Hiring a top-heavy line-up comes in the distant third.
