Depends on model, promt and amount of agents that review. I found that default code-review in Claude code is pretty mid for finding all issues especially if you downgrade model and effort.
During my evals on my own 3 agents that review in parallel they are much more cost efficient and cover 75% issues. Even on model like haiku it’s better score than default.
Multiple passes or raising effort will cover 90+. And this was tested on large diff, about 3500 LoC changes
