ChatGPT edges Claude on aggregate — 91 vs 87.

The Swiss Army knife of AI -- if you only pay for one AI subscription, this is the safe bet, but power users will outgrow it fast. Claude still wins for buyers who prioritise 200k+ context window. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
