I feel like Opus 4.7 vs GPT 5.4 is pretty much just flavor variants, the big difference is in the harness. I like the Claude Code CLI better than the Codex CLI, it just clicks with how I like to interact with agents. The codex app on the other hand is better than the Claude app in code view, so if I had to stick to an app it would be codex all the way.
