What's better than GOG Galaxy?

Right now I am running GOG Galaxy in bottles and it is mostly stable. However, I don't like how GOG Galaxy constantly is showing ads and harvesting data.

What I am looking for is another Windows launcher that can manage GOG games. Ideally it should be simple and work with a controller.

I also need an alternative to the cloud sync. I think it might be possible to either use Syncthing to sync folders or to setup a network share and then use some scripting to save my progress once I'm done playing. The biggest issue I have is that I don't know how to import my GOG cloud saves into the offline installer.
