I think there's no single right answer... and there's not even a single answer: my favorite editor usually depends on the component I'm working on, and it's very common that I have opened at the same time Atom, VS Code and IntelliJIdea (the 3 I use the most). If I have to look at some CSS edition, Brackets is great but I really don't do it very often.
VSCode is great for Typescript, IntellijIdea is great for Scala, and Atom is really nice for so many languages that's it's my usual sandbox ;-)
(And that's only for web-related code editor, RStudio is my other sandbox as soon as I have anything maths/stats related to do)
