ChatGPT vs Claude vs Gemini: Which AI Is Best in 2026?

There's no single winner — at an identical ~$20/month entry price, the right pick depends on your primary workflow. Claude wins for coding (SWE-bench #1, Claude Code) and long-document analysis (1M-token context); Gemini wins for cited research (native Google Search grounding + Deep Research) and Google Workspace users; ChatGPT wins for general-purpose breadth, native DALL-E image generation, and the best voice mode.
