Do LLMs actually struggle with real or opinionated thinking, or am I using them wrong?

I have been trying various tools for some time. i have mixed experiences and would love to know what people here prefer here for intellectual and opinionated discussions. chatgpt gives the best answers but it often gets stuck on a point refusing to move away even when given evidence or definitive proof against it. basically stubborn. tries to play safe too much. gemini straight up sucks for me even though it works good for structured and non opinionated research or tasks.
