I think that Godot GUIs are very limited compared to HTML+CSS. It’s not a huge problem for videogames since screens sizes aren’t going to vary as much as for a web app and you are probably going to make a lot of changes anyway when porting to something like mobile. But it would never work well for proper responsiveness on different screens.
It’s definitely not perfect (and definitely not a replacement for web apps) but I think it’s a big step in the right direction for GUI development. People have made impressive programs with it.
