I'm an extensive user of both. aider was the best a few months ago -- claude code is substantially more performant and easier to work with as a dev, regardless of aider's underlying model.
Between claude code and gemini, you can really feel the difference in the tool training / implementation -- Anthropic's ahead of the game here in terms of integrating a suite of tools for claude to use.
When I have a difficult problem or claude is spinning, I usually would use o3-pro, although today I threw something by Grok 4 and it was excellent, finding a subtle bug and provided some clear communication about a fix, and the fix.
Anyway, I suggest you give them a go. But start with claude or gemini's CLI - right now, if you want a text UI for coding, they are the easiest to work with.
Have you tried the codex CLI? And how does it compare to those other CLI agents if so?
The Codex CLI feels a lot more unpolished than the others. If you look at the repo's commit history, they're in the middle of a rewrite. The CLI often tries to involve calls on the Codex model using APIs that don't exist anymore. It's a mess.
It is model agnostic however.
