What I use for: I use for identifying duplicated code. It is deterministic, doesn't use AI, offline, runs from CLI and is super fast (and free).

What I dislike: I won't say it I dislike, but it is not a tool that does all the jobs of a code review. For instance, it doesn't flag security issues. It is superfocused on code duplication (it performs better than Sonar for this use case) and is specifically useful for large codebases.

As my daily driver at home, I use Pi though because it doesn't get in your way and forces you to understand how the sauce is made.

its rather theoretic, papers instead of ai apps, but might be useful. Fe if code review in your organization is used to sync people - ai assisted code review might be not helpful. Or if you value evolvability/maintainability/simplicity points in good review - agents won't help here with additional knowledge base either.
