The mobile builds are its killer app, in my view as a gamedev. Unity has lost the plot in many ways. Desktop builds are important too, but there's competition there if you consider browser/electron as a desktop platform, plus Unreal. But Godot is the exclusive up-and-coming competition in mobile builds (that I am aware of; granted I am not a mobile dev).
