I skipped using aider, but I heard good things. I needed to work with large, complex repos, not vibe codebases. And agents require always top-notch models that are expensive and can't run locally well. So when Codex came out, it skipped to that.

But mct leverages the weak models well, do things not possible otherwise. And it does even better with stronger models. Rewards stronger models, but doesn't punish smaller models.

So basically, you can use save money and do more using mct + codex. But I hear aider is terminal tool so maybe try and mct + aider?
