OpenAI stuff in general seems (to me, at least) to be overly positive and confident in terms of how it replies.
While I make no foolish claims that it's perfect, I've found Claude feels much less arrogant, and was genuinely appreciative when one of its replies started with an (accurate, of course I checked primary sources to verify that) analysis of the first half of my question, and then for the more obscure second half said "I'm not sure if I can answer that without hallucinating, but here's some stuff you could try researching."
Certainly Claude's tone and "attitude" (FSVO) works much better for me than any other LLM I've tried, though mileage will, of course, vary.
(I have zero connection to the company and am still on a free account, I'm just quietly impressed relative to the competition)
