I like using Codex inside OpenCode, but frankly most times I just use it inside Codex itself because O.Ai has clearly made major improvements to it in the last 3 months -- performance and stability -- instead of mucking around trying to vibe code a buggy "game loop" in React on a VT100 terminal.

I had been using Codex for a couple weeks after dropping Claude Code to evaluate as a baseline vs OpenCode and agreed, it is a very solid CLI that has improved a lot since it was originally released.

I mainly use OC just because I had refined my workflow and like reducing lock-in in general, but Codex CLI is definitely much more pleasant to use than CC.
