Aside from the benefits of open-source, I also find that Godot has a nicer workflow for me, with nodes and signals that make it really easy to make games. I also like that GDScript is very similar to Python (so it's a lot simpler) while also having the option for explicit data types. The code editor is also built into the engine which is nice. The documentation for Godot is also excellent (it truly is really good), not to mention integrated into the engine as well!
