2. She's not the best singer (sorry pebblephiles, but chumbuds do have a one-up on you. Gura had the voice of an angel, while Biboo is vocally mid at best)
3. Some of the things Biboo has done, Gura did better (again, she can never be Gura's true replacement, because no one can be (see 5))
4. Her penchant for soulslop kills some growth (Souls becomes very niche especially after 10+ hour long playthroughs)
5. No COVID buff (this only really applies to Myth, but please consider this)
That said, and desu, to have 920k despite not numberfagging is VERY impressive. Many Gura-killers (Yuko Yurei, Komachi Panko, Petra Gurin) WISH they could have a sub number that high, as they usually would numberfag hard just to maintain their audience.
Biboo will get her million soon, but I do think she needs to do something really spectacular. Or make such an impressive improvement on her singing that there'll be a sudden jump; I'm not a believe in talent as I believe more in perseverance and hard work, but I do think Gura was actually a trained singer and child entertainer unlike Biboo. Biboo will have to grind even more to truly match Gura's level
