I've really struggled with using the extensions - their UI/UX is worse, they're much more limited in what they can do and they're much more unstable (in IntelliJ at least).
Then again writing mostly kotlin I cannot get along with the VS Code forks as they're just not that great outside of typescript projects in my experience.
I tend to prompt in cursor/windsurf and refactor in IntelliJ which is okay but a bit of a pain.
