> The new Siri isnt that exciting at least on my iPhone 15 Pro Max

On my Pro 16 it has its ups and downs - I still can't get it to "play my running playlist on shuffle" whilst running (this is the only thing I used Siri for before the beta and it would improve my life immeasurably if it worked). But it responds to things like "how long will it take to drive to the AirBnb booking in my inbox", and "when is X playing a concert in Y - add a calendar entry with details" perfectly.

This is a beta and I have hopes, but I can imagine it will run better on a 17 and later

The best models for new Siri, on device, requires the iPhone 17 Pro, so your experience on a 15 is going to be degraded.

I use it on my 15 pro max. It's a major improvement, but I still don't use siri much. It's gone from murderously infuriating to passably usable. I still use gpt for any sort of exploratory conversations. I haven't bothered trying to use siri for that because to me that's not what siri is for.

Although given how effed up the voice for chatgpt is now with the latest updates I might talk with siri more.

Because I use carplay in tandem with my phone where the map is on the carplay screen and turn by turn directions are on my phone, it's always unlocked so I haven't run into whatever lock screen issue you brought up.
