They all look to be within the same ballpark; none of those startup times would be a problem for me, at least. But when I tried Atom it was noticeably less responsive, which I have very little tolerance for. I haven't tried VS Code. (I also use Sublime)

My experience is that VSCode is much more responsive than Atom.

Just a lot "snappier". Startup is not much of a problem, I don't open ordinary files in VSCode or Atom by default (I use gedit for that)

Showing a window is in the same ballpark, but being ready for input is something else. On Sublime this is basically the same instant. On VSC and Atom it takes a bit longer to actually render a cursor.
