Which one fits you
You want one agent for knowledge management, content creation, and automation beyond coding, and want to keep the option to switch away from OpenAI models.
You're deep in the ChatGPT/OpenAI ecosystem, mainly write code in a terminal, or want Codex's official cloud/IDE surfaces working together.
