I had a great experience with it refactoring a project to use more modern patterns. A Go project moving from a deprecated and unwieldy query builder to using SQLC and protobuf for UI types etc. It did a great job just working its way through the entire system.

Had less luck on generating new features. It's great for prototyping UI but I routinely end up writing it myself.

It's also quick to forget how I like to do things or what libraries and packages it should use. So I either have to keep reminding it or fix up the work myself. While I'm unsure whether it still ends up being quicker, that's really immaterial for me because it absolutely kills the enjoyment of the work.
