Yeah it's weird, almost like we're seeing two cults form in real-time.

I imagine there's a benign explanation too - the intelligence of these models is very spiky and I have found tasks were one model was hilariously better than the other within the same codebase. People are also more vocal when they have something to complain about.

In my general experience, Opus is more well-rounded, is an excellent debugger in complex / unfamiliar codebases. And Codex is an excellent coder.
