Sublime is really snappy and responsive. But it also doesn't have as many fancy automation like jetbrains. Maybe that keeps the code "real", rather than some artifact that you have the computer manipulate for you.
This is the main reason I've ever found myself using it if not vscode or now cursor. If I have some massive file that needs messing with nothing handles it as well as sublime does.
That’s definitely part of it. Though even before I start typing and am just looking at the characters on the screen, they seem more dense, tactile, and real. Is there a categorical difference for how Sublime renders text vs other editors out there?
