What do you use for code reviews?

Question

I've been reviewing PRs on GitHub for a few years now and it feels primitive. For one, looking at diffs alone makes it hard to spot issues like modifying a function signature breaking the function on another file.Are there any useful tools suited for code review?

I've started just running git diff --stat first and reading the most-changed files in full instead of only looking at diff hunks. The surrounding context matters way more than the change itself and GitHub actively hides it.
