I've extensively used both iPhones and Pixel phones for years.
Siri is astonishingly, infuriatingly bad. It's hard to imagine anyone on the Siri team uses it daily like I do. It works well ~30% of the time and is bafflingly non-deterministic.
Google is much, much better, but it's still not objectively great. It's closer to 80% of responses being reasonable, which is still unacceptably low.
