>>93223538I'll try to actually give a serious answer.
1) You have a ton of god gamer content on the internet, but usually it's men. This is cute girls being good at games (there are various levels of skills within vspo). When you see them doing good in some casual tournaments where pros an ex-pros play too or even subbing in for someone in an actual tournament with pro teams and doing good, it's pretty cool and makes, at least me, wanna cheer them on. And since they're vtubers, it's not only about the games. They sing (some of them well, some of them try their best), they chat, and do a bunch of other things too.
2) Most of them are just being themselves. Over the time, I got a bit tired of vtubers that keep playing a character most of the time. A lot of them don't mind talking about stuff that goes on in their life or episodes from the past, so if you listen to their chatting streams, you get to know them pretty well. A lot of them also have interesting personalities and most of them are surprisingly good at chatting with viewers. I say "surprisingly" because you might expect gamers not to be very good at talking.
3) They have a strong sense of unity and it feels good to see that. It's fun to listen to them having fun together when they for example hang out and have a takoyaki party.
>>93225186VSPO also have kino concerts and karaokes.
VSPO also has better video quality for concerts because they know how to stream in 1440p unlike the agency with the state-of-the-art 2.7B yen studio.
What do they have to offer? Pretty much anything that hololive can offer to you except for big group concerts.
