I'm not a regular follower so I don't have a lot of history to base it on, but based on the streams I've caught, it just seems well balanced— like the presentation is definitely not "sexy" in the way of, like, a hot tub streamer, but it's also not completely locked down and soulless— there's personality and shenanigans in the way of a radio host or commentator, and also a lot of great chess-playing.

Another good example is Xyla Foxlin, who walks a similar line with a YouTube engineering/maker channel and has been very explicit about her approach: "I refuse to “act more like a man” in order to achieve legitimate and respectable success in the professional world. I happen to be someone who embraces her femininity and feels powerful in cute shoes and sparkly makeup, and I don’t see how any of that makes me less of an engineer." [0]
