As a recent convert to git and a long-time Emacs hacker I'm wondering what other serious Emacs/Git hackers recommend for git support in Emacs23. I've already started using the VC git backend and find it somewhat of a thin abstraction layer of git's capabilities. So I'm inclined to try another. Googling turns up a half dozen or so choices in addition to the standard Emacs VC support.
If you prefer magit or egg, why? And if your recommendation has platform dependencies, how so?
