I'm a hipster and didn't care for Coco during her Hololive time, either.
Then again, my Holo favs are Suisei, Marine, Aqua and Subaru. I don't think that gets a lot of hipster credits...
Lots of Holos throw games for content, whether single- or multiplayer. Okayu. Miko. Aqua (only when it's Sora's on the other side, else she sweaty gamers everything). Noel (her Zelda gameplay is a meme, I know. Consider that she did two simultaneous playthroughs of Link's Awakening. One on stream, and one deathless for the true ending, of which we saw only the very end). Koyori (whose gameplay is always awful and just barely enough to get by, whether she's playing Super Mario World or Ghosts 'n Goblins). Pekora herself does it on a routine basis, too.
So of course she picks one of the ones who'll take pleasure from stomping their competition regardless of whether it's a pro player or a toddler.
