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.
