Am I the only one who has no performance issues with Atom, except on insanely big files? I don't like my files to be 1000+ lines anyways (where possible) because it severely impacts readability/skimability.

ST3 might win me back when Package Control is integrated, but until then, Atom is more than fine. IntelliSense on VS Code looks really powerful, but it's personally a feature I do not enjoy.
