Verdict

Pick Cursor if your daily driver is an AI IDE and you want editor UX, Tab completions and (on Premium+) Cloud Agents/Bugbot—knowing new signups buy The X Subscription (Premium $30 is the usual Claude/GPT-capable tier, with third-party models billed at API list price). Pick Codex if you already subscribe to ChatGPT Plus ($20) or Pro and want OpenAI's agent in the terminal and cloud without switching editors. Existing Cursor Pro ($20) subscribers can keep that plan; new buyers cannot.
