For the languages I've used it with (Python, Rust, Javascript), its introspection is without compare. Ie the ability to understand what's going on with the language, and use this to catch errors, refactor, and autocomplete. Its project-based-design (vice file-based) is a better fit for most of my code as well. From my perspective, JetBrains can get away with being slow due to how much better it is at core features than any competitor.
