I genuinely think that gen 3 fractured when Rushia was kicked, as clearly Pekora still holds positive sentiment towards her while Noel/Flare do not. Add onto how something seemingly happened between Noel and Flare as well, given that their pairing has been dead for a few years lol. Meanwhile Marine has basically fucked off since losing Aqua/Shion/Ao/Kanata, at least she still does covers and original songs I guess but her streaming frequency has been non-existent. So it’s really just Pekora still chugging along, seemingly thrusted by her continued rivalry with Miko for who can maintain the position as top Holo
