This is a fascinating aspect. I also find much more usage out of Claude code and its willingness to go along with my ideas and be “steerable” seems to be part of it with codex many times it kept on overwriting changes I told it to make. It’s a clear kind of disagreeableness trait in action. Makes me think!

I find claude models often use “tricks” like bash one liners, essentially excelling at surgical fixes. It does what i want more reliably, on smaller tasks.

GPT-5 can often be better at larger architectural changes, but i find that comes at the cost of instability/broken PRs. It often fails to capture intent or argues back, or just completely spirals out of control more often.

GPT-5 codex seemed to refuse valid requests like “make a change to break a test so we can test CI” (it over indexed on our agents.md and other instructions and then refused on the basis of “ethics” or some such)
