Key features that matter to me:
1) backup from android or iOS. This helps when I have switched phones over the years.
2) shared albums with family or friends where invited people can both see and contribute photos. Think kids albums, weddings, holidays.
3) ability to re-download at full resolution
1) You don't have backups of other data on your phone (chat history, 2FA secrets and private keys, text notes, anki cards, game progress, configuration of all apps, etc.)? I had assumed everyone who cares about their data has backups of their data anyway, so that's not really a selling point to install another app for
2) that's nice!
3) "it doesn't throw my data away" is the last selling point?! Isn't that just assumed?!
1) I do have separate backups, as well as this, which runs more frequently (after picture is taken) vs daily for device backup
3) not compared to iCloud photos which I migrated from. You can export a whole album with Google at original quality with 1 click. With Apple you can only do 1000 at a time. For apple you can ask for a whole account export, but that takes a few days and gives you all photos. (Similar to Google Takeout).
The backup thing is really more than just backing it up. I take a picture, and it’s nearly immediately available in the same way across all my devices and the web. I can search for “pizza” on the web app and see any picture of pizza I ever took. On a different or new device I’ll immediately have access to the whole library with no set up.
