Fauna is only funny to desperate, lonely men. She steals half her jokes from Northern Lion, the other half of her "content" is nostalgia baiting, the lowest form of content, even lower than react slop. She appeals to pseudo intellectuals (see her entire "String theory explanation" clip, in which she absolutely butchered the explanation of string theory) who fancy themselves intelligent, but in reality are no more intelligent than Redditors. Her ASMR is so mid it's painful; she bought a 10,000 dollar microphone accessory only to deliver ASMR that could easily be replicated on a 50 dollar Blue Yeti.
If you want a quality chuuba who not only loves her audience but also does ASMR significantly better, I recommend Pillow. Unironically just a better, more interesting version of Fauna. Wouldn't even be fair to call Pillow a copycat because she mogs Fauna so hard the two aren't even comparable.
