As someone who actively used Claude 3.7 Sonnet Max, I’ve completely stopped using it. Now, I only use GPT-4.1, because honestly, it performs even better than the MAX version.
Gemini still has ongoing tool issues, while GPT-4.1 is currently amazing at logical reasoning and code refactoring — it solves the required parts quickly without writing unnecessary lines of code. It’s also very effective at analyzing code.
With MAX, I often couldn’t get the answers I needed, and it would result in massive and unnecessary code changes. Since switching to GPT-4.1 (especially using Agent mode), that problem disappeared. Sometimes it solves what’s needed in just 10 lines of code, whereas Claude would bloat it into 200–300 lines for no reason.
So, my honest recommendation: use GPT-4.1 in Agent mode — it’s currently the best. It’s extremely useful for visual analysis, problem detection, writing minimal code, and handling complex algorithmic tasks.
GPT-4.1 is the BEST!
