The ranked list
Stripe holds the consensus #1 at a score of 75, with Claude and Gemini and Perplexity placing it first outright.
My genuine default recommendation for a U.S.-based online business is Stripe—unless you are already committed to Shopify, have substantial in-person sales, or operate at enterprise/global scale.
ChatGPT, this closeStripe – The default recommendation for most online businesses; its developer-friendly APIs, extensive documentation, and flexibility (from simple checkout to complex marketplace/subscription billing) make it the best all-around choice for startups and scaling companies alike.
Claude, this closePayPal ranks #2 on consensus with a score of 64, scoring best on ChatGPT (#1).
PayPal — Best added as a checkout option alongside card processing, since many buyers already trust and use PayPal or Venmo, though I would rarely make it the only processor because its standard online-wallet pricing can be comparatively high.
ChatGPT, this closePayPal – Still the most recognized and trusted brand among consumers, so offering it alongside another processor can measurably boost checkout conversion, even though its fees and dispute policies are less favorable than Stripe's.
Claude, this closeSquare ranks #3 on consensus with a score of 49, scoring best on ChatGPT (#1).
The models disagree about it more than most: #1 on ChatGPT but #4 on Perplexity, a spread of 3.
Square — Best for small businesses that sell both online and in person, thanks to its simple all-in-one POS, invoices, payment links, APIs, and transparent no-monthly-fee entry option.
ChatGPT, this closeSquare – The strongest choice if you sell both online and in-person, since its unified dashboard, POS hardware, and online store tools sync seamlessly.
Claude, this closeAdyen ranks #4 on consensus with a score of 46, scoring best on ChatGPT (#1).

Adyen — Best for larger international and omnichannel merchants that need a single enterprise platform for global acquiring, local payment methods, fraud controls, data, and in-person payments.
ChatGPT, this closeAdyen – A top pick for larger or international businesses because it offers unified global payments infrastructure with strong support for local payment methods and currencies.

How are these rankings measured?
We ask each model the same buying questions on every run (1,560 queries this period), record the full answers, and score each named brand 0-100 by how early and how consistently it appears. Every question runs through the official model APIs, with web search on, not through the consumer chat apps, so nothing is personalized to a user. Each model is scored independently; the consensus blends all 4.
Do the AI models agree with each other?
At the top, yes. Every model crowns the same #1 at the latest close. Further down the board they diverge, which is why each brand carries a spread figure: the gap between its best and worst model rank.
