She aint no Gura, but yeah I dont think anyone else will be able to pull her numbers in EN, maybe IRyS if she streamed more often.
I think for the sake of comparison it's also important to remember a few factors that were also generally at play with Gura's viewership numbers. Not to diminish her popularity because obviously she was the most subbed holo for a reason but just the "grain of salt" to take the information with when comparing her to her peers especially when talking about who could sort of fill that void after her departure.
Inconsistent streaming can definitely have a negative effect on someones viewership and how the youtube algorithm handles them we've seen that effect the doggos to a certain extent (along with the niche game choices etc) but at a certain level, if the gaps in streaming are on the larger side like Gura's often were you can get sort of the opposite effect. where every stream suddenly becomes a big deal because "holy shit she's actually streaming everyone get in here" which actually increases average CCV.
Think of it the same way where if a member goes on an extended break, when they return their first stream back is usually much higher than usual viewership, but in Gura's case she was riding that kind of thing long term, and also pairing it with many times when she'd pop back up out of the blue, it would be surrounding some other big event, Her Birthday, Her Anniversary, Another member graduating, a Major holo game arc (like the rust streams) or events like new debuts or graduations.
These sorts of things make it hard to really estimate what her "normal" ccv might have ever been if she just streamed normal, I think it still would have been high, and likely the highest in EN , but I do think she would have settled a bit lower in her average viewership like the rest of EN did over the years too if not for that "rarity buff" on when she would actually pop up to stream.
Numberfags are like a gayer, dumber version of sticker niggers. I can understand wanting to see your favorite streamer be successful, but this is supremely autistic.
I think one of my favorite things in recent years to see from the denizens of /#/ was when Mori's song Overkill came out, a song in which the lyrics are explicitly a middle finger to the "horse race" mindset being taken with talents. And the autists of /#/ said with a straight face "haha this song isn't about people like us, it's just a shot at company managers!" despite mori herself after the song released saying the message applies to "some fans" as well as corporate suits who only care about analytics and not the talent themselves.
