Here is Google Nest's comparison of the 1st gen and 2nd gen doorbells:

We are still using all three of our 1st gen Google Nest Hello Doorbells, even though the internal battery has failed on all three (necessitating turning off the "Indoor chime" option and relying on the "Visitor announcements" option instead), and even though we have silicone "skins" on two of them because the fronts are peeling. The aspect ratio on the 2nd gen doorbells is 3:4, yielding a taller and narrower view, unlike the wider 4:3 aspect ratio on the Nest Hello. In addition, because the 2nd gen doorbells work only in the Google Home app, they lack numerous Nest app features (https://support.google.com/googlenest/answer/13038234#zippy=%2Cnest-app-only-features), especially the Enhance (zoom) feature, which is very helpful for us since two of our doorways are recessed.
