I prefer o1. I mostly use it as a knowledge system. Don't really care for the automatic code generation nonsense. Unless I'm really tired and the task is very simple, in which case I might decide to write a paragraph of text instead of 30 lines of Python. My experience is that when ChatGPT fails, Claude fails too. On some advanced coding tasks, I find ChatGPT's depth of reasoning ability to be better.
Out of curiosity, could you give an example of 30 loc python code that would require a lot of text to describe? I usually find that high level descriptions with maybe one iteration with refinements work surprisingly well if the assistant has knowledge of the context.
