It’s starting to feel like people need to say what language/stack and problem space they’re working in. It would be interesting to see why we’re seeing such wild variance.

I primarily use composer. I wanted to build something from scratch recently and, thinking I was missing out on something, I got Opus to build it. I wasn't blown away. I gave the same prompts to composer and the code it came up with different but similar in quality. I ended up progressing with the composer code because it was easier to progress with improvements due to its faster response time.
