In my experience (which certainly does not reflect everyone's), Atom wins in performance these days, too. Startup time is a bit slower, but once it's running it's quite snappy. It feels... less like a webapp than VSC does, if that makes sense.
VSCode is better for most people; it's a great editor, and does more out of the box without configuration. However, if you're someone who DOES feel the need to tweak everything until it's just right, VSC doesn't hold up. JSON configuration is just clunky. Atom is, at least in some aspects, scriptable without the need to build a full plugin (though it's certainly no emacs), and that's quite valuable. And, when you introduce the atom-ide package, the gap in completion and debugging functionality between the two gets quite a bit smaller.
Also, anecdotally, Atom seems to have had better performance across my machines; especially on lower-end hardware. I'm only working on small-medium sized projects, so this might just be me.
Atom is much closer to Emacs; nearly all the functionality is provided through optional packages, and it's very open to little tweaks to make it just the way you want.
