I'd say it depends, though I suppose the same could be said for Blender vs Cinema4D. Overall, if I had to put a number on it I'd say a 7, however that cuts both ways, I could say that Godot is 70% as good as Unity or that Unity is 70% as good as Godot.

I migrated from Unity to Godot a few years ago because its open source, but now even if Unity went the same way I doubt I'd go back. The only things I really miss about Unity are the solid features for 3D (but Godot is getting there) and the choice for using a generic, performance orientated language over a built-in, ease-of-use orientated language (which I don't see changing anytime soon, though mono support is improving). That last one is especially important to me, but I'd be more likely to move onto another open source engine/framework than back to Unity.
