Our experiences diverge surprisingly far. The new Siri was worse for everything I use it for before I turned it off.

The new Siri can not reliably return the weather (it seems it's prompting on the literal text of the town and asks for a clarification sometimes about whether I am in the United States or United Kingdom), and when I ask "what is the air quality index", the new Siri would sometimes return the definition of AQI. When it returns a value, new Siri would hallucinate an incorrect and fixed value. In the cases where it does work, it's very much slower than the classic "rainbow orb" Siri.
