Yes they are, the fact that the agents have full access to your local project files makes a gigantic difference.

They do *very* well at things like: "Explain what this class does" or "Find the biggest pain points of the project architecture".

No comparison to regular ChatGPT when it comes to software development. I suggest trying it out, and not by saying "implement game" but rather try it by giving it clear scoped tasks where the AI doesn't have to think or abstract/generalize. So as some kind of code-monkey.
