Smaller generations of girls with behavioural oddities and deficiencies, to not only make them more relatable and pitiable, but also more likely to remain dependent on the company. Pretty much any Holo right now could ride their current success into a nice career as an indie, but with the exception of Suisei, I don't think they could keep proper schedules or maintain their momentum without contractual obligations and management. They'd end up crashing and burning in the long run, they're all at least a little menhera that way.
Ichikara also employs interesting personalities, but probably prioritizes hires with a demonstrable knack for entertainment. As a result, while they employ a greater variety of skilled talent, and more readily allow them to display their abilities on streams, the freedom Nijis are given means the unstable ones are at a risk of falling by the wayside, while the proactive ones may begin to see vtubing as a springboard to jobs elsewhere, and not a career in itself. They incubate driven people like Chitose and Gibara, who come to recognize their own potential outside the vtubing scene.
The motivations are probably very different for the companies. Cover relies heavily on superchat revenue from Hololive, while Ichikara wants to show off their AR/VR/3D tech through Nijisanji and can afford to lose a few stars. For the fans, it's down to your priorities; Hololive does GFE and the "one big happy family" feeling better, while Nijisanji provides entertainment in the form of superior dancers, singers, gamers, comedians and so on.
