I’ve been running it for a couple of months. It’s under active development, but I personally feel that it’s stable and at a good enough place to be a full replacement of Google Photos. In fact, I turned off all uploads to Google in their Photos app, and rely on Immich auto-uploading to my server instead. Of course that means having a robust (preferably off-site) backup and disaster recovery plan.
