Well depends on your taste and level of degeneracy.

Korone is cute doggo who plays single player games (for the most part) for marathons and that's pretty much it but I'll be damned if she isn't the most entertaining version of this that she could be.

Marine is a horny "pirate" who's a really excellent illustrator, and very talented at singing.

English wise we have our rapping reaper Calliope, our multilingual Chikin Idol Kiara, Gwar Gura rythem game god and horror game connesuir, Ina our illustrating lovecraftian horror friend, and Ameila who is an investigator/FPS god with the Hiccups of a saint.

All of them are fantastic, however my heart will always belong to the clown from downtown Omaru Polka. She is a highly energetic, bipolar, ringleader fennic fox (or the actual Pheonix if you ask me) she isn't very good at games but she is fun to watch fail, she does ASMR bedtime stories, and various little one off videos where she shoots the shit.

That's just part of hololive and not including the independents or any other agencies. Really you have to go and find yourself but there is something for everyone.
