Does Photos have features you use that Immich doesn't? I've switched to the latter fully and love it (though I have an Android).

Music and AI features are still lagging in Immich, and I can understand why. Immich machine learning is not flushed out yet. If Immich has plans for creating marketplace for extensibility like plugins, in the current era of Claude code, I am sure we will end up with many options or features.
