Seconding this. Legitimately better than Google photos in a lot of ways, even if you don't care about the data ownership aspect. If you've ever been annoyed at how Google Photos handles face detection / grouping, you'll love Immich.
Thirded. Immich has no right to be as good as it is after such a short time. Completely took down my google photos, finally, and I still have face recognition, word search and automatic backup from my phone.
