That's weird. I can prompt 2.5 Pro and Claude Sonnet 4.5 about the same for most typescript problems and they end up doing about the same. I get different results with Terraform though, I think Gemini 2.5 Pro does better on some Google Cloud stuff, but only on the specifics.

Is just strange to me that my experience seems to be a polar opposite of yours.

I don't know. The last problem I tried was a complex one -- migration of some scientific code from CPU to GPU. Gemini was useless there, but Claude proposed realistic solutions and was able to explore and test those.
