SpaceX is reportedly buying Cursor for $60 billion. Anthropic is shipping Claude Code updates every two weeks. Every developer I know is asking the same question: which one should I actually use?

I spent the last 90 days shipping production code with both. Not toy projects. Not benchmarks. Real features, in a real codebase, with real deadlines. Here's what each one is actually good at — and where they both fail you.

I'm not going to give you a feature table. You're smart enough to read the docs yourself. What I am going to do is tell you what happened when I made each tool do real work.

I started with Cursor because that's what everyone was using. The tab completion was the hook — once you get used to it, going back to regular IntelliSense feels like typing with oven mitts.
