Ask the internet whether ChatGPT or Claude is better for marketing and you may accidentally join a sports rivalry.
The useful question is smaller: which tool produces better work for your team, on your tasks, with your constraints?
Product capabilities and plan limits change. A result from someone else’s screenshot is not a procurement strategy. Run a short comparison you can repeat.
Use the same brief
Choose three real tasks: a landing-page draft, a customer-interview summary and a campaign critique. Remove personal information and anything you do not have approval to upload.
Give both tools the same approved material: audience, offer, evidence, voice examples and required output. Do not give one a detailed brief and the other “write something good,” then declare a scientific breakthrough.
Ask both to distinguish supplied facts from assumptions. Tell them not to invent customer results, prices or product features.
Define “better” before you see the answer
Score factual accuracy first. A charming paragraph with a fictional guarantee is not a strong result.
Then score usefulness, specificity, voice and editing time. Use a simple one-to-five scale with examples of what each score means. Hide the tool name if a colleague can review the outputs independently.
For a landing page, useful criteria include whether the offer is clear, objections are addressed and the call to action matches the buyer’s readiness. For interview summaries, check whether important dissenting comments survive the summary.
Include a deliberately difficult task
Give the tools incomplete or conflicting information. Perhaps the offer document says one turnaround time and the sales notes say another.
A good response identifies the conflict. A weak response chooses the nicer number and hopes nobody asks.
Also test a revision: “Cut the introduction in half without losing the buying context.” Marketing involves editing, not merely admiring first drafts.
Compare the work around the answer
Check your actual account’s sharing, permissions, connected tools and review process. A slightly better draft may not justify an awkward handoff.
Anthropic‘s small-business offering and OpenAI‘s workspace agents both reflect a broader move toward connected business workflows. Availability and account requirements should be checked directly before choosing a setup. Anthropic · OpenAI
Our suggested decision rule: choose the tool that clears your quality threshold with the least total effort. Using both is reasonable if each has a defined role. Paying for both because the internet is shouting is less convincing.
Keep your briefs and scorecard. Repeat the test when your needs change, not every time somebody posts a new leaderboard.
