>>20386485If I had to judge vtubers on their skills, I'd use three axis: cuteness/charisma, entertainment, and miscelleaneous talents (singing, video game, art,...). There's no magic recipe for success. Gura is the most suscribed and she's carried by cuteness. Pekora is the most watched and that's because she's a great entertainer.
You're wondering if cuteness alone can lead a chuuba to success: yes. But it's not as easy as only having a cute voice and model. Mannerisms, personality,... are even more important and it's not something you can easily copy without looking like a tryhard.
