I use both. For me AI is like a broad brush, good for generating a lot of code or making sweeping modifications until it fits my standard and requirements.

Then the iterating starts, making targeted improvements, and I think at this point it's a wash because I can be much faster than AI as it will take multiple passes to do something efficiently and concisely.

But I think this is contingent on deep familiarity with the code and project.
