Honestly, having access to resources like Doki does, and wasting her opportunity to have at least one sexually appealing feature on making it a "gag toggle" is why she's always going to be second rate. Think about it, Hololive girls know that most of their fans are going to be men, and have designs that show abundant fertility. They understand that having obvious sex appeal brings in new viewers, helps build a large following. They're not trying to be "ironic" and act like they're too good to appeal to male audiences, they're straightforward about it and it makes them better idols. Girls like Nerissa and Kiara give you an actual reason to start watching them and stick with it, unlike Doki where your reward for watching some fucked up BOTW Link in a cowboy outfit is getting to hear stories about stupid shit interrupted by laughing every 5 seconds.
Meanwhile, Dokibird is completely fucking unable to take any of it seriously. Her "lore" is half-assed shit about being a actually being a tomato, her design looks like a boy, and she wasted her one chance to bring some actual feminine appeal into it by treating the most sexually appealing feature she had made for her as a "joke" with her signature irritating laugh the whole time. She's fine with her core fanbase being full of dykes who used to watch nijisanji because she has no problem with essentially coasting as long as she never has to actually make a real effort to appeal to men. But guess what? Maybe if she didn't refuse to take what men would like to see in a vtuber seriously, she wouldn't be getting hard mogged in CCV even by Mint, who is a boring as fuck Hololive reject but at least she actually shows some feminine appeal.

I know it's AI slop but my god I have jerked off to this photo set of her so many times. She looks fucking perfect.
