Ok it was not just me then.

I use both. NP++ for like single documents or quick kanban lists for myself. VSCode is better for a group of closely related items such as when using it as an IDE. As I do not keep both open all the time NP++ usually wins on startup speed. Which fits my workflow.

I think they wrote "lightweight text editor" but really they meant lightweight editors, with a loose classification of full-blown IDEs as heavyweight and everything lighter as lightweight, VSCode being the heaviest in the lightweight category.
