Same here. I replaced the few Alexa devices in my house with Homepods over the last year and have notice no difference in how well they work because I don't use them for anything particularly complicated, and I don't _want_ to use them for any more than that. The only thing Siri seems to mess up for my usage is not interpreting things I put on my shopping list correctly, but usually in a way that's still recognizable (like "milk this'll").
-set alarm -next song -set timer -set reminder (e.g. "Siri set reminder 6pm close garage door") -send message to <person>
These comprise 99% of what I would want it to do, and it does it marvelously.
