Short answer: Claude is usually better for long-context, careful synthesis and claim-tracking; ChatGPT is faster and has stronger plugin/retrieval options. For 30–50-article weekly briefs, run Claude with temperature=0, require inline citations, a claim-tracking table (claim → source snippets → confidence), and a bibliography. Do a 2-week A/B using the same inputs and score on accuracy and traceability.
