Claude Code is a commodity at this point though.
Codex is just as good if not better. And theres 3-5 other options out there just as good too (harness + model).
I disagree. I've tried Codex, and two of the provider-agnostic harnesses (Pi and OMP), and I strongly prefer Claude Code.
Opus 5.5 is the best deal in doing rn. It will change soon. But its not the case that codex, etc are equivalent
