Claude is terrible. I've been using Codex for a few months and decided to give Opus a try and see how it is.

After asking it to review a single file in a simple platformer game, it goes:

> Coyote jump fires in the wrong direction (falling UP with inverted gravity)

    var fallVelocity: float = body.velocity.y * body.up_direction.y

> I owe you a correction: after re-analyzing the math more carefully, lines 217–223 are actually correct — my original review point was wrong. Let me walk through why.

Oh boy. It's had several other gaffes like this, and the UI/UX is still crap (fonts don't get applied, it doesn't catch up with the updated working state after editing files etc.) Codex helped me save time but Claude is just wasting my time. Can I get a refund?

Do you find Gemini or ChatGPT or Grok to be better?

I am currently using Claude as I find it to be better than the others at the free tier.
