I’ve been using sublime since forever as well; Atom never really felt like a valid alternative because it was so so slow. VSCode still feels kinda slow but not to a degree that gets to be annoying. Still I could never get used to it. It breaks some system keyboard shortcuts that I use heavily (alt + arrow keys for example) and takes forever to parse files (to make a list of all functions in the project for example).
I wish sublime would update more often and have all the cool new things that come to VSCode every other week, but at the end of the day it still works better and doesn’t really lack anything that’s actually useful (except maybe for a few months before st4 came out).
