RedHatOnTopSome claim that 5.3 Codex is better than Opus 4.6, what are your thoughts? 中发帖

I saw some people claiming that GPT-5.3-Codex is better than Opus 4.6, and some doesn’t seem to agree. I didn’t try out GPT-5.3-Codex just yet, so I don’t really know how good 5.3 Codex actually is. What are your thoughts; which is better for your usecases? How are your experiences with both models?
