Same for me. I have not yet successfully used an LLM to generate code to produce a feature, though to be fair, it might just be because I don't have the patience to go back and forth with it (will readily admit that I am using it wrong).

Also, while some code review comments are just plain wrong, LLMs did produce some damn good comments, on the same level as a different senior engineer might note had they taken the time to study the code carefully.
