I once tried to download my Google photos, and it became super messy. I got tons of different folders all with duplicates and other stuff and it was pretty unusable.
One of the positives of the Google+ shutdown was that Google Takeout saw a major overhaul around February of 2019. Third-party tools (Alois Bělaška's Friends+Me was invaluable https://blog.friendsplus.me/) still proved very useful, and gave capabilities missing from Google's offerings.
Has this improved?
