Maybe the HomePod (original) can compete with the Sonos One or Five at sound level but not in terms of features people are looking for listening music such as: virtually all music streaming services available, integration with all the remaining Sonos products for Home cinema or for Home sound system.
To me Homepod Mini is after the home assistant market. The HomePod (original) well it seemed like a shot in the dark now it will most likely get the Homepod mini features.
Google and Amazon need to work harder to get presence so they push them out using aggressive pricing.
So yeah, as I expected it's Amazon's game, Google trailing but a strong presence, and Apple virtually missing from the race.

Beyond that piece of functionality, Siri is still a very developmentally disabled assistant and has never proven useful in my experience.
