I LOVE Immich. Been using it for a few months now, first on a Raspberry Pi 4 and then an old x86 box. Before Immich I had tried for a while to use Photoprism with Syncthing to sync photos from my phone, but the transition to that from Google Photos was a frustrating one.
Immich on the other hand expressly tries to be a Google Photos replacement, and while I initially thought that was an audacious goal for a fresh open source project to have, I have been pleasantly surprised by how feature-rich it has become in a short amount of time.
I know the developer makes it very clear that it's not stable yet, so I'm making sure I back up everything from my server at regular intervals. But I've found it to be more and more stable with new releases, so hopefully a first stable release is not far away.
Can I ask what specifically you like about it over Photprism? Just the sync?
I've also been questing for a Google Photos replacement, and right now Nextcloud functions admirably for auto-sync but like garbage for anything past that like viewing albums afterwards. I've had an instance of Photoprism up for a while and was debating bringing it into "production" on my homelab.
The biggest one was that Photoprism doesn't have a mobile app. It seems a lot of people use PhotoSync (a third party app) to back up to a PhotoPrism instance, but I didn't even want to give it a shot considering they don't offer the premium features on Android. Immich on the other hand has apps that are developed together with the server and web UI, so everything is well-integrated.
