For general 2d development, Godot is much better than unity already. It doesn’t have everything that unity does but what it has is much more efficient and easy to understand.

Though the opposite is true for 3d.

In short: Unity is a 3d tool where you can pretend one of the dimensions doesn’t exist to make 2d games (but it’s still running a 3d environment behind the curtains, you’re just not seeing one of them), while godot is a 2d tool that gives you an optional third dimension for some stuff.
