I'm most familiar with Unity so I'll speak on that. Unity itself offers the editor (can be configured), debugger, asset manager and visualizer all in the main client. Some people have built external tools on top of Unity for things like no-code game building but the vast majority of developers directly use Unity.
I think Godot is probably the most unique of the ones you listed in that it seems like the one you might can mix and match different tools together but I'm overall much less familiar with it.
