I really find it to be more annoying than helpful. The mental burden of figuring out what the code is actually doing when a large chunk appears is exhausting, and it leaves me with a false level of understanding similar to the feeling of competency you get when you type out a tutorial's examples.
Underwhelming is how I'd describe my experience with ChatGPT too. There are so many people making claims of ridiculously improved efficiency, that I'm really unsure if it's me or not.
