VSCode is the newest editor in the list, and nowadays, developers are not so attached to their editor.
I think that VSCode's popularity is due to the fact that people are curious.

I used WebStorm, switched briefly to Atom and then quickly to VSCode.
Atom had fewer features than WebStorm and felt just as sluggish :/
