Cursor in agent mode is the same thing as claude code and codex. And now Grok 4.5 included into subscription. It gives you more value, since grok is cheaper and faster version of the Opus.

I also want to believe that Cursor team working on harnesses for much longer then openAI and Anthropic can deliver better results overall. Claude code is being pretty much vibe-coded slop doesn’t give a feel of a good product.
