Mainly the plug-ins, particularly third party plug-ins for unity are better.
One of them being cinemachine.
Another example would be a tool call technique collider creator that let's you paint collider primitives. That tool alone saved about 300 hours of work.
For many developers the Cinemachine tool is very useful as well.
The other feature is the ability to edit game objects while the game is running in editor mode for debugging. This is the sole major feature Godot currently lacks compared to unreal and Unity imo
Beyond that Unity has a better overall design IMO encouraging users towards composition over inheritance and NOT encouraging use of some one shot interpreted scripting language (GDscript)
Does this justify the 100x greater size of Unity as an organization over Godot? Probably not
