My answer is that I tested both, and Claude Code (~8 months ago) was so obviously better than Cursor that I continue to happily pay Anthropic $200/month. Based on anecdotes I happen to catch, I don't believe Cursor's caught up.

The value isn't just the models. Claude Code is notably better than (for example) OpenCode, even when using the same models. The plug-in system is also excellent, allowing me to build things like https://charleswiltgen.github.io/Axiom/ that everyone can benefit from.
