ChatGPT is best chat bot for now, IMHO… It’s ok to explore themes, philosophize... It’s not so heavily censored, it imitates logical thinking process very good. But at the same time it lies sometimes – distorts names of books, gives bad links, leads you astray with technical staff, like electronics and administrating… It’s nice to argument with it but when getting tech solutions and advice one should be cautious. Also it loves throwing rhetorical garbage.
Gemini. Very helpful in technical staff – short and precise. Good in programming. Worse with electronics than ChatGPT. Didn’t chat a lot with it, so do not know how "well spoken" it is, but generally feels neutral avoiding bold conclusions. Great addition to conventional Google Search.
Grok. Have mixed feeling of it. Very helpful with system administrating. In programming sometimes better than ChatGPT, but as a chat bot it is censored and avoids controversial topics. Even when cornered logically, dodges arguments to stay tolerant, which is bad.
Perplexity. Brief and straight to the point. Didn't used it much.
All local LLM models, I tried, suck… But maybe large ones for very powerful GPUs are OK, though I have no inclination to invest in hardware right now.
We can't rely on AI opinions, but as support and augmentation to idea exploration AIs are OK.
