Disagree.

I end up using ChatGPT for general coding tasks because of the limited session/weekly limit Claude pro offers, and it works surprisingly well.

The best is IMO to use them both. They complement each other.

I use OpenCode and I made an "architect" agent that uses Opus to make a plan, then gives that plan to a "developer" agent (with Sonnet) that implements it, and a "reviewer" agent (Codex) reviews it in the end. I've gotten much better results with this than with straight up Opus throughout, and obviously hit the limits much less often as well.
