I share your frustration. I found a workaround that solves it for me: When I want to talk to my phone or my watch I don’t say “Hey Siri” anymore, I just hold down the lock button (aka use it the old way). That activates Siri on the device without triggering any other devices. Since I generally have my watch or phone at hand, this has solved the issue for me. Still I wish the detection for “which device am I talking to” was better.
