I'm still on Sublime Text, after briefly switching to VSCode. Unless you're on latest-gen hardware it seems that most feature-rich IDEs are just terribly laggy, which drives me nuts. A computer just shouldn't need several seconds to load and parse a source file even if it has 100.000 lines. Editors like Emacs or Vim were always too low-level for me though, Sublime is a nice compromise between simplicity and speed.
