Hololive fans are creepy, disgusting, disturbing people who form a toxic parasocial relationship with a livestreamer and treat her as their "virtual girlfriend". That's the experience hololive provides. They use emotional manipulation to solicit donations, and make you emotionally dependent on them. That's downright emotional prostitution.
Vshojo is just a bunch of fit young lads who like hot chicks. They're far more normal and mentally healthy. "Boobs? Looks good to me!" They don't pretend the vtuber is their virtual "oshi", they don't form a relationship. They just like watching sexy girls stream.
