The AI coding tools market has evolved towards agentic workflows. Claude Code excels in complex engineering tasks like multi-file refactoring but has high token consumption. GitHub Copilot is ideal for low-latency, single-file autocomplete, while Gemini Code Assist effectively handles long-context tasks and large repositories without forceful edits. Proper tool selection is crucial.

A hands-on comparison of three AI coding tools based on real-world use across large repositories. Claude Code is recommended for complex multi-file refactoring and architectural changes, but burns tokens fast. GitHub Copilot remains the best low-latency IDE autocomplete for single-file, day-to-day coding. Gemini Code Assist shines for long-context analysis of massive codebases where conservative, non-destructive suggestions are preferred. The key takeaway is to use all three in a tiered approach rather than picking a single winner.

Comparison Summary: Which Tool for Which Task?

Interesting, a post about AI, written by an AI but not without it’s baises I would say. For fun I asked my AI provider to guess which AI wrote this, and it said Claude because, well, it’s obvious.
It DID however say that a GPT would’ve done a better job, but then ChatGPT was what I used so I think it’s being biased
That was fun.

This is the kind of post I love to see. As my earlier mentor told me early in my carreer: “Each tool has it’s usage. You don’t take a hammer to screw a wardrobe onto the wall.” and as John Romero said on the WeAreDevelopers Congress in 2019: “PHP doesn’t matter that much, the tool doesn’t matter, it’s what we solve and do with the tool.”
While both are quite contrairy in their meaning, it comes to a unified meaning: Do stuff, and do it with the thing that is best for you to solve it.
But on a side note: Why that post image, now I want a second breakfast :D
