I'm back on Claude Code this month after a month on Codex and it's a serious downgrade.

Opus 4.6 is a jackass. It's got Dunning-Kruger and hallucinates all over the place. I had forgotten about the experience (as in the Gist above) of jamming on the escape key "no no no I never said to do that." But also I don't remember 4.5 being this bad.

But GPT 5.3 and 5.4 is a far more precise and diligent coding experience.
