You are missing an entire agentic experience. And I wouldn't call it vibe coding for an engineer; you're more or less empowered to truly orchestrate the development of your system.

Cursor has agent, but that's like whoever else tried to copy the Model T while Ford was developing it.

This hasn’t been my experience at all. I’m finding Cursor with Opus 4.5 and plan mode to be just as capable as CC. And I prefer the UI/UX.
