Claude handles long documents with tighter structure and lower hallucination risk on factual claims. ChatGPT has wider plugin/function access and stronger coding/math consistency. For weekly long-form writing, Claude is usually the cleaner drafter. For mixed weekly workloads, ChatGPT may consolidate more tools.

Weekly workflow test

Run the same real task in both tools for one week. Score on: time-to-first-result, corrections needed, export/import quality, and monthly cost at your expected volume. The winner should be obvious by day three.

Decision summary

• Pick the tool that fits the weekly job you actually repeat.
• Keep the other only if it covers a different workflow you cannot do otherwise.
• Set a 30-day trial for the runner-up; cancel unless usage is weekly and verified.
