for regular use, OpenAI just somehow seems faster, more straight forward and it remembers the context better of the whole chat, also I use it a lot for links and analysing pictures, where Bing did disappoint me more, at the end of the day seems just user preference tho, with Bing you have to do more research around the answers, where with OpenAI you can just kinda chat and move on like that
I pay for OpenAI, but I also experiment with Claude and other, because I’m not dedicated to OpenAI, just started with it
