The vim plugins in atom completely blow VSCode's out of the water. It's split up into two packages ('vim-mode-plus' for most of vim, and 'ex-mode' for handling ex commands), but they work together very well.

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.
