Ditto, I love JetBrains, but cannot ignore Cursor. I use the IntelliJ shortcuts / Darcula extensions to help with familiarity.

Among the ones you mentioned, I also tried Gemini Code Assist JetBrains extension, but it doesn't integrate anywhere close to what Cursor does. (Direct code inserts, rollbacks, checkpoints, context integration) Zzzzz come on JetBrains
