You're right, because Godot's GUI tooling is incredibly beyond anything Unity offers (and I say that as someone who primarily uses Unity). Unity's GUI solutions so far are plagued by terrible performance on the common usage scenarios, terribly undocumented when it comes to making your own components, and the layout system is simply a big mess. While Godot's isn't anything particularly worth praise by itself (especially when compared to dedicated UI toolkits), the simple fact that creating a simple 2-screen interface does not melt a mobile device's CPU puts it far beyond Unity. That, and the layouting is relatively saner. So much so, that at the company I work for (which is sort of consulting, not products), when we need to do 2D or UI-heavy games, we go to Godot, to the extent of training Unity developers on it instead of trying to make do with Unity's UI. I do agree on the other points though, Godot is still very young as a community and so the asset store is pretty vacant.
