Which wired doorbell is best if I'm in the Google Home ecosystem versus Alexa?

For Google Home / Nest households, the wired Nest Doorbell (2nd or 3rd Gen) is the natural fit, with native Google Assistant routines, Gemini event descriptions on the 3rd Gen, and free three-hour event history. For Alexa users, Ring's wired lineup integrates most tightly (announcements through Echo devices, Alexa Greetings). Arlo, Reolink, and Tapo all work with Alexa and Google Assistant but offer less deep integration with either.
