I transitioned to NijiEN long ago.
They're great and they have a lot of fun together, but you do have to understand they aren't for unicorns. They collab with males, they have no rules against dating or even marrying. Most of them are mature enough not to talk about their sex lives thankfully. If you're a unicorn you're gonna have a bad time, that's just a fact.
There are some other smaller corp EN's you can check out. Pippa is one of a kind, and appeals mostly to /pol/acks. Lumi is Pippa's friend and does strategy games. Amiya is for boomers who like watching retro games from before the year 2000. Lisa really likes music, you can also get parasocial with her.
I haven't checked out the Kawaii girls, but they just got some new debuts recently that could be promising. And Tsunderia has some debuts planned in the near future. As for Prism, they have a couple people that might be worth checking out, I would recommend Sara for Australians.
Unicorns are definitely up a creek though. Maybe you can find some indies, although most of them go the sluttuber route.
