I agree that Claude can be very preachy and frustrating. But I disagree that DeepSeek is the most neutral. I think it is actually the least neutral because the censorship is by design and forced by the government. Claude basically has clumsy safety features that are not sophisticated to stay out of the way but without malicious intent, unlike DeepSeek.
Deepseek > Chat-GPT = Llama >>> Claude.
Deepseek seems like a neutral tool. Claude is very, very preachy. I'm happy that there doesn't appear to be any reason to ever use it again.
