Why are (you) still watching Hololive if it pisses you off so much?
Let's examine some common complaints surrounding Cover and Hololive and see if they apply to Nijisanji.

>EOPs in the chat are so obnoxious!
Due to Nijisanji being relatively unknown in the west, even the chats of popular Nijis like Lulu are still 99% Japanese.
>Cover doesn't do enough to help their talents!
Immediately after the Aloe situation occured and she graduated, Ichikara implimented anti-slander measures against their talents, responding to the situation faster than Cover.
>Cover doesn't do enough for Holostars!
Nijisanji promotes their male talents equally as much as the girls as there is no segregation by sex, with the most popular vtuber of their's being Tokyo Ghoul himself - he's also the most subscribed to male vtuber period.
>Hololive doesn't have enough lolis!
Nijisanji has several loli in their ranks, including an aptly named Loli Gumi consisting of 4 (four) separate loli talents.
>Cover half-asses their 3Ds!
Nijisanji 3D productions are big events and treated as such without blatant model rigging issues or cheap, bought unity asset backgrounds being on display.
>Cover censors their talents too much!
Nijisanji isn't an idol company, so what their talents are allowed to talk about is far beyond the scope of Hololive. Shotacon talents are open about thirsting after shota talents, dirty fanfic Maros are read on stream and talents are free to be honest with their viewers as they don't need to pander to paypigs.
>None of Hololive's yuri couples are real!
Nijisanji has a real lesbian couple that are openly dating.
>Hololive stopped making swimsuit streams!
Nijisanji has no problem showing their talents in skimpy clothes in 3D streams or otherwise - they aren't afraid of getting demonetized as merch makes up the majority of their income.
>Hololive's concerts are too expensive for it's content!
Nijisanji always gives their all and puts on amazing 3D concerts with high production value, even those done for free.
>Hololive talents always play the same games!
Nijisanji has a far broader range of permissions and variety of games played regularly, with Atlus and Sony permissions being a particular strong point.
>Kiara exists!
Kiara does not exist in Nijisanji.

So, what's the reason for your loyalty towards Hololive?
