VS.Code users aren't exactly casual users and in the main are happy enough to use it as their main coding interface many hours per day (and yes I understand that this is HN so now there will be a bunch of people saying "I'm not happy).
Ironically Jetbrains IDEs are Java, using Java Swing for the UI[1]! This is even less native than VS.Code where at least native widgets are used.
I guess this shows how much our impressions are formed by expectations!
Simple experimental proof: resize the window to be very small, and open a menu. The menu can't go outside the bounds of the window.
On my laptop (6 core 3,9GHz 32GB RAM and NVME) VS Code is fast and responsive, still wastes lots of RAM though. Jetbrains tools meanwhile were way more laggy on the same setup.

And I dream the day that React Native for Windows/Mac team at Microsoft manages to force a VSCode rewrite.
