Personally speaking the git diff command is great for output, but can be improved for reviewing.

With difi the TUI made for git diff it allows to me speed up the review process and make it more enjoyable.

For the nvim integration, there already exists diffview and code diff, but I still favors the github website's solution of highlighting + and - inside one file rather then side by side.
