The best in terms of coding assistance, and really for anything else, is the original (pre-turbo) GPT-4 used via the API, although this will also be more costly. There are many third-party chat apps that are wrappers around that now if you want a ChatGPT-like experience.
This can also significantly reduce its bias since you are in control of the system prompt. But also, even ChatGPT can be trivially made to behave differently by saying that you're writing a book or making a video game etc, describing a character in it, and then asking it how that character would have responded in such and such situation.
