In my experience the new Siri is marginally worse for everything that I used to use Siri for. It's much slower to respond. It asks for obnoxious classifications. It doesn't know that when I say "call Mike" I mean the Mike I call every day vs the other Mike in my contact I have never called in my life. It defaults back to Apple products for everything, old Siri knew I liked Spotify but now if I ask it to play a song it will complain about my Apple Music subscription. I could go on.
