For me it's the other way around, when I see someone using an IDE instead of a lean editor I see their struggle. Multiple seconds to open the IDE (sometimes tens of second), multi-hundred millisecond lag when opening a file, noticeable input lag. And when you have to edit a file your IDE doesn't understand, all you have is a bloated notepad.
I know I'm biased and I intentionally wrote this one-sided to counter your post. In practice, it just depends. Right now in my work I primarily edit scripts (up to a few hundred lines of code), do quick edits to various larger projects - sometimes few different projects a day - and read files in dozens of programming language (I only reall program in Python and C/C++, but I have to constantly consult various weird pieces of code). VsCode works great for me.
On the other hand, long time ago when I was working on large C# projects, I can't imagine not using Visual Studio (or Rider nowadays I guess).
