I also have both and also use Codex as my daily drive. I still vastly prefer it to CC both for the quality of the code it writes and much better limits, but in this last week, I feel like it's gotten much dumber as well. I normally bounce back and forth between 5.3 Codex high and 5.4 high depending on the task and I've started finding so many mistakes in 5.3 Codex's code which is a major change from even just a few weeks ago. 5.4 high still gets the job done, but even there, I feel like it's taking more steering and input on my part for even simple tasks.
