Comparison to rclone with google-photos backend

[wscott]

One other option for downloading photos is to use the google-photos backend of rclone to download pictures. I don't find anyone that compares photos-sync with rclone. It would be nice to link to a page/issue/wiki from the top-level Readme with a comparison.

Background: I have used gphotos-sync in the past in a cron, but have recently been using TrueNAS-Scale and they have rclone support built in. I wonder if that sync would be equivalent or if I should set up some container to continue using gphotos-sync.
