On the other had, they have also slowly destroyed their app ecosystem. The photo solution is much worse than it used to be both in terms of features and the now removed support for media codecs. Video station has pretty much been dead for years.
At this point, I'm not that convinced that there's anything that synology offers that isn't handled much better by an app running on docker. This wasn't true 10 years ago.
The photo apps is great because their photo backup app on android is great, and the only thing that works as well as google photo to ensure all your photo and videos are saved, untouched, no duplicate, no missed media.
That's it. For the actual viewing / sorting / album you need something like immich or photoprism, the photos app actually sucks.
Video station has been removed in the latest minor update, not even a major update, they just took it out no warning no replacement. But then again it was not that good, jellyfin is the way to go for me.
Their crown jewels are active backup, hyper backup and synology office. That's where they own their space.
