For coding in my experience Claude Sonnet/Opus 4.0 is hands down better than Gemini 2.5. pro. I just end up fighting with Claude a lot less than I do with Gemini. I had Gemini start a project that involved creating a recursive descent parser for a language in C. It was full of segfaults. I'd ask Gemini to fix them and it would end up breaking something else and then we'd get into a loop. Finally I had Claude Sonnet 4.0 take a look at the code that Gemini had created. It fixed the segfaults in short order and was off adding new features - even anticipating features that I'd be asking for.

Did you try Gemini with a fresh prompt too when comparing against Claude? Sometimes you just get better results starting over with any leading model, even if it gets access to the old broken code to fix.

I haven't tried Gemini since the latest updates, but earlier ones seemed on par with opus.
