I used Cursor for about 5 months before switching to Claude Code. I was only productive with Cursor when I used it in a very specific way, which was basically me doing by hand what Claude Code does internally. I maintained planning documents, todo lists, used test driven development and linting tools, etc. My .cursorrules file looks like what I imagine the Claude system prompt to be.

Claude Code took the burden of maintaining that off my shoulders.

Also Cursor was/is utterly useless any all non-Anthropic models, which are the default.
