Why the Choice of AI Tool Matters

The three major AI assistants — OpenAI's ChatGPT, Anthropic's Claude, and Google's Gemini — are all capable of helping engineers with a wide range of tasks. But they are not identical. Each has different strengths, different failure modes, and different pricing structures. Choosing the right tool for the right task makes a meaningful difference in the quality of output you get. This comparison focuses on what actually matters for technical professionals, not on benchmark scores.
