I like that I can ask more nuanced questions without getting dumped to a web search, and I can have a back-and-forth conversation.
But timers and smart home actions are definitely less reliable and sometimes take absurdly long to respond (like 20-30 seconds p99).
Your experience is valid of course, but I never once have had the inclination to have a conversation with my phone. I'm not sure which of our experiences is more common.
