I’ve seen a lot of recommends for Immich on here, so I have an idea what the answer here is going to be, but I’m looking for some comparisons between it and Photoprism I’m currently using Synology Photos, and I think my biggest issue is it’s lack of metadata management. I’ve gotten around that with MetaImage and NeoFinder. I’m considering moving to something not tied to the Synology environment.
In the sense that immich warns not be the only way to store your pictures, while Photoprism advertises as a bug-free program, that adds new features very slowly in order to be bug free.
Makes sense. Though if one wants security maybe it's better to use something like PhotoSync to copy the photos through FTP/anything and mount the volume RO.
