I used to be a hard-core command line only (no fancy shmancy UIs here GitX!) git user. I have also been an emacs user for 23 years. Since I discovered Magit I will not touch command line git anymore. It's that good. Single key-press for all major features, easily add arguments the same way, and q quits any temp buffer for viewing. Diffs and reviewing history is a breeze. It's exactly what I would expect git + emacs to be. If you haven't tried it, do so and give it some time. There is a cheat sheet here:

That should get you well on your way to using Magit.
