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).
