Honestly, I don't know why anyone would use ChatGPT over Bing ai, bing uses GPT-4, is free and is available in many more countries.
I personally see ChatGPT without up-to-date information as useless, even at programming tasks, bing searches for the syntax and standard, then suggests something, instead of just making everything up.
And when there are complex questions, it relies on its previous searches to answer.
Also the modes are useful, the accurate mode, does what it says, I have never caught it making stuff up, while creative mode is much more willing to do stuff and create images using the Dall-E 2 integration.
Your data, the same thing with openAI, none of the current AI offerings are privacy respecting, unless you count open source AI, which isnt really comparable.
