I tested ChatGPT vs. Claude to see which is better – and if its worth switching

Here’s another topic I’ve been meaning to research. My dad wants to gift a property to my brother, but he doesn’t want to involve lawyers, and my brother wants to avoid high upfront costs. They’re not sure how to proceed. Can AI break it down clearly, with sources and links they can use to verify the information?

Test prompt: “My dad wants to transfer a mortgage-free house in Malone, NY, to my brother without a lawyer. They want to minimize upfront costs. Explain the best option step by step, with sources, including what they need to do, where to go, which forms they need to complete with official links, and the expected costs.”

Results

In ChatGPT, I selected Deep Research. It started processing my request, but warned I was out of messages on the “most advanced free model” and would switch to a less powerful one until my limit reset in three hours. After waiting 40 minutes for a report to generate, I ran a normal search instead, which returned results instantly.

Claude also kept spinning and saying it was still working. To finish the test and keep it fair, I switched again from the default Sonnet 4.6 model to the faster Haiku 4.5 model, and that finally worked.

Both said my brother’s best option was a quitclaim deed. They said he needed a notarized deed, linked to the required forms, explained where to file them, and estimated his costs. Both said there is no state transfer tax, but neither mentioned he could owe capital gains tax if he later sells, which I know from past experience.

Claude’s answer was more scannable, but it had fewer sources. At one point, it cited the New York City Bar Association for the quitclaim deed, even though we are not in New York City. ChatGPT was more detailed and included far more sources, though some were random, like Legal Clarity and Avenue Law Firm. More importantly, it got a key detail wrong. It told my brother to file in Clinton County, but the property is in Franklin County.

Because of that, I have to give Claude the win for accuracy.
