I gave it a try a few months ago. Unfortunately, my experience was not that great. I was hosting it on Synology through Docker and found that the iOS client was a bit buggy and quite slow. Synology Photos completed the initial sync in a few hours, while Immich took several days. After a few months, I switched back to Synology Photos. I might try Immich again in the future.
I started looking for alternatives after Synology became more restrictive with their hardware. I'm curious if anyone else has had a similar experience.
