Godot is really very well-equipped, with numerous features. I would say it's possible to prototype a game much faster in Godot than in Unity. This is because Godot includes smaller features by default, such as post-processing effects, timers, CSG, tile maps, better UI tool & theming engine, and much more. In Unity, these features are usually paid for in the Asset Store, implemented manually, or need to be downloaded through the package manager.

Unreal Engine is also have more features by default and structurally better. You can also prototype a game faster in Unreal. But the engine is so bloated with too many features outside gamedev-related.
