xdelta is nice
delta is a nice little tool you can strap into git to show deltas in the terminal in a much nicer fashion. It'll syntax highlight the code, and background shading to indicate add/delete/mutate of lines and then within that highlights word add/deletes. Optionally, it'll do split screen side-by-side diffs and/or show line numbers. Overall, it produces output much more like Critique/Gerrit/etc and much more readable than git itself. It's rather great, I should have adopted it many years ago.
